What exactly is the "geometrical basis" of the Pivot moving parallel to the Delivery Line?

I find it intriguing that Homer refers to "Parallel Pivot" as a "therapy" (similar to the way he uses the term in the 'exaggerated inside-out Cut Shot Therapy' as a drill to cure Steering. See 3-F-7-A) because it's something that should happen anyway, and it's also hard to exaggerate.

What are the "three motions" Homer was referring to that lifts the Clubhead above Plane?

Has anyone tried this drill on students?

It looks like it would be good for those that get outside the plane, or "over the top". Looks like it might cause those that tend to get too shallow... to get even more shallow.
