Lynn's Swing and left wrist

[ndwolfe81]

So I came across this video and I have a few questions.

Here is the video

Ok, after impact it certainly appears that his right wrist flattens and the left wrist bends. As his hands are going to the finish it looks like the left wrist is still bent.

This looks very different than the wrist alingment that he shows in the finish swivel.

Thoughts?

Is the bent wrist more correct for someone who fights pulls?
