I'm a beginner in the TGM game so take that with a grain of salt but what striked me with the flying wedges concept is how much this defines the plane and make a solid resilient structure. The right arm flying wedge provides a strong support for the left arm flying wedge, similar to the waiter-holding-a-tray image but not only at top, during most of the backswing and downswing. It also seems to support the shaft during the impact interval (optimize club head speed at separation?) and since the right forearm is on-plane, it supports a forward, downward and outward impact. I imagine the right forearm as a support rod for the inclined plane, maybe even defining the plane, and freeing the left side to do its business.. and only that.

If we had to keep the club on plane using only the left arm, it may build tension in the left forearm and might prevent a good release of acc #3. This is just an hypothesis.
