Correction: Not likely - do you think they shot off the real Roger Moore's fingers? Remember, the whole area is on a huge raised scaffolding, movement around the room could cause the dummy to sway.

The mistake is valid. After Scaramanga performs a ground somersault and shoots the mobster, you can see Roger Moore's right hand moving before the shot suddenly freezes. If the floor were truly unstable, his entire body would be shifting - not just his hand. The rest of the scene is a mix of Roger Moore, dummies, stand-ins, and prop body parts. (And no - the actors are never actually shot at. It's just a movie.)
