Overextension - fault or not

In this video: www.youtube.com/watch Dave Scott talks about four common faults: head position overreaching overextension dropped elbow In this video: www.youtube.com/watch the videographer analyzes Ian Thorpe's stroke, and while I disagree with much of his analysis it is great slow motion video of Thorpe. BUT, Thorpe enters his right arm fully extended with the elbow and forearm actually entering the water just before the hand does, see attached video frames. This is exactly what Dave Scott describes as overextension. I am wondering whether it actually makes any difference how you enter the arm if you are fully extending the arm before starting the catch? The end of that second video is trippy. It's like the matrix, man. That aside, if you look at 8 swimmers, you'll see 8 different entry points. That's really one of those things that you have to test to see what works best for you.
