Revealing: Watch the line appear on the wall as Kelso cuts through the wall into the "Luxury Suite." The line is being cut with a round, drywall cutting bit such as would be used with a drill or Dremel tool. You can see it spinning as the cut is made. However, when Kelso has pushed down the wall and points the tool at Cox and the Janitor, he is now holding a standard reciprocating saw with a flat blade which would cut very differently than what was shown.
