My first thought in dealing with the "Sequential Release" is that the Left Arm Wedge is Vertical at Low-Point and the Right Forearm Wedge is On-Plane (Dynamically Inline). So, the Wedges are Aligned at 90 degrees for the Clubshaft to "Release" while aligning to Both Planes simultaneously, so that the Clubshaft can be moved successfully on the Swing Plane. So,there are three Planes to reconcile.

WOW. If we were designing the Golf Stroke from the ground up I think that people would raise some serious issues with the difficulty of that. But actually its really simple. The only difficulty is describing the On-Plane necessities as outlined above.
