What you are talking about is back and forth editing, and since most dialog scenes are not shot with coverage of both people at once this is normal. What canofhumdingers is talking about is isolating actors WITHIN the same shot--if there is a wideshot of two people, Lucas would digitally rotoscope Liam Neeson from take 3 into a shot of Ewan McGregor from take 1, so that both actors oncamera at the same time are not actually oncamera at the same time but spliced together from different takes of the same shot.

I see. Thanks for the correction.
All I know is that Peter Jackson combined different performances and the visual continuity got thrown off. Plus I'm pretty sure that I remember watching a behind the scenes feature where Jackson talked about using the best performances from multiple takes.
