The left wrist ideally- normally - stays flat not only through impact but through the follow-through and through the swivel. That is one of the fundamental alignments.

How the right wrist moves while that happens is of lesser importance. That said, it normally flattens from impact to follow- through- certainly on full shots...But the real judgement is up to you- look at alot of different swing sequences of professional players- not just one here or there. See if you see the right wrist flattening between release and the follow-through.

This contradicts what has been posted by the Doctors on these TGM-related forums over the last 4 years.
