Deliberate mistake: Blofeld doesn't recognize James Bond in this film, even though they met face-to-face in the previous movie, "You Only Live Twice." There is a production-related reason for this. Ian Fleming wrote "On Her Majesty's Secret Service" in 1963 (in which Bond and Blofeld met for the first time), and he wrote "You Only Live Twice" in 1964. However, "You Only Live Twice" was adapted for film first (in 1967), and "On Her Majesty's Secret Service" was adapted afterward (in 1969). Because the 1969 film was so faithful to its source material, Blofeld and Bond are basically meeting for the first time... again. The producers were aware of this continuity problem and intended to have James Bond undergo plastic surgery for "On Her Majesty's Secret Service" (which would conveniently explain Blofeld not recognizing him, as well as the fact that Sean Connery had been replaced by George Lazenby in the lead role). But the plastic surgery idea was discarded in faithfulness to the novel, resulting in a glaring continuity problem between the 1967 and 1969 films.
Continuity mistake: When Blofeld escapes riding the bobsleigh, there are several shots of him sliding way along the slope, then we see Bond firing the last shot and now the bobsleigh is right at the starting point.
Continuity mistake: When Bond knocks out Che Che there's a rectangular piece of white furniture next to the bed. A shot later it has moved a meter to the left, pink slippers now visible, and is now on top of Che Che's leg.
Revealing mistake: When Bond slides along the ice he is very obviously grabbing a cable that pulls him along.
Continuity mistake: Hilary Bray's hands are lowered on the front shots, but raised in the side shot. (00:47:10)
Continuity mistake: Bond's car drives to the beach covered in dust. When it's parked it's spotless.
Revealing mistake: While the lab explodes, Blofeld jumps a ditch followed by Bond. Bond's stunt is noticeable because of his longer and light brown coloured hair, as opposed to Bond's very dark colour. (02:11:40)
Revealing mistake: When Blofeld escapes from the Lab, Telly Savalas is replaced by an obvious stunt wearing a bald cap that protrudes around the forehead.
Continuity mistake: When Bond approaches Tracy to give her flowers, her sleeve stands out of the window or not, depending on the shot. (02:19:20)
Revealing mistake: When the thug is stuck to the spikes on the wall, the protruding safety pad under his clothes is very noticeable.
Continuity mistake: When Bond is ordering breakfast, the position of his hand on the phone changes between shots. Check his index finger.
Continuity mistake: Position of the nightgown on the bed when Bond fights against Che changes between shots. (00:15:05)
Continuity mistake: After Bond knocks out Che Che there's a close-up of him feeling dizzy and collapsing unconscious. Shot changes to a wide angle, and he repeats all previous movements.
Continuity mistake: When Bond is in his room fighting against Che Che, a table leg lies on the couch, but disappears in further shots.
Continuity mistake: At the beach, Bond lies down on the boat and kicks Raphael while aiming to sit up. A shot later he's lying down again.
Continuity mistake: After Tracy's car passes Bond's, check the stones and constructions on the left side of the curb. Shot changes, we see the car speeding away, and then the shot cuts back to the previous place where the car was.
Continuity mistake: When Bond is finishing up copying the documents in Gumbold's office, with Gumbold about to return via the elevator, a clock tower is shown at 13:59. Without the shot changing, the hands immediately move to 14:00, but some pigeons nesting on a ledge below abruptly change position. (00:42:58)
Revealing mistake: When the white race car with the number 6 is turned over there is a closeup shot of the driver obviously hanging head down in his seat. If you look closer you can see the spectators in the background also upside down. (01:47:20)
Revealing mistake: When Irma Bunt is firing shots from her gun in Blofeld's car towards the end of the movie, Blofeld is a dummy and not Telly Savalas.
Continuity mistake: When Bond started his escape on skis he has laced ski boots. When he throws the guy off the cliff and resumes skiing, he has buckled boots.
Answer: It's an entirely intentional aside to the audience, the one occasion in the entire Bond series where the so-called 'fourth wall' (i.e. the cinema screen itself) is broken. As such, within the context of the film itself, it doesn't really have much of a meaning.
