I don't know why you state that a hinging action only lasts for the duration of ball-clubface contact. It is my understanding that a hinging action continues to the end of the followthorugh (when both arms are straight) and that there can be no clubface roll-over towards the ground during that time period - because that would represent a swivel action and it is my understanding that a swivel action should only occur during the finish phase of the swing and not during the followthrough phase of the swing.
