During the Backstroke, the Left Arm Wedge Turns (Single Wrist Action) or is Turned (Standard Wrist Action) to enable the Vertical Wristcock Motion to occur on the Inclined Plane. This is the 'palms parallel to the Plane' alignment necessary for the Top (8-6) and Finish (8-12) movements involving Wristcock.

And herein lies the paradox I've been trying to solve. If the Vertical Wristcock Motion occurs on the Inclined Plane, lets say the Turned Shoulder Plane, this means the entire Left Arm Wedge is also On Plane. But this cannot be the case since the Right Shoulder defines the Turned Shoulder Plane. What am I missing here?
