Another excellent description/analysis by Jack.I think this also relates to the motion analysis data we have discussed here before.

If the body does not rotate well sequentially/segmentally,then there has to be excessive torque to compensate for suboptimal rotation which means the backside has to get overactive as the arms extend and the wrists roll,usually creating high swing timing error and a swing that decelerates and reaccelerates and is still accelerating at contact (the typical acceleration pattern of the long "linear" swing).The rotation is too much the one piece "spinning" type with out good creation and transfer of momentum, and part of the compensation ivolves the of the backside action/"collapse" to power the back arm.This is consistent with the observations in this old post which mentions the "side bend to the trailing side":
