In regard to your last paragraph. I am not sure Biomechanic Analysis supports your position. That said some studies have indicated the lateral shift occurs prior to the completion of the backstroke.
I guess the question I have is when does the latteral shift occur since this sometimes occur prior to the completion of the back stroke (change in direction) while others seem to do it prior to the downstroke but when it appears the back stroke is completed. Then there are all those others who are still doing it at some undefined time during the down stroke but not consistent (hackers, golfers developing a stroke, etc.).
