The easiest solution for a contrary opinion would be to put up or point out swing sequences where the left arm flying wedge is on-plane as you described. After all, if the left arm flying wedge is on-plane then the left shoulder would be on-plane.
Although the Left Arm Flying Wedge often is not On Plane, I do not agree that it is "normally never on the swing plane." For example, Full Extension of the Primary Lever (Left Arm and Club, aka Zero #3 Accumulator) should occur in almost every Stroke immediately after Impact. Clearly, when this condition exists, there is a theoretical Left Arm Inclined Plane (Photo 9-2-11 #2). Another On Plane Left Arm Flying Wedge could occur on the Downstroke when both the Left and Right Shoulders are On Plane (Photo 9-2-8 ).
Nevertheless, the many variables associated with this subject demands great precision in writing, and my earlier post needs some correction. I will write again on this issue when I can devote the necessary time. Meanwhile, check out the Down-the-Line view of the following Moe Norman sequence.
