I find that 10-18-C description very interesting and very new to me - as it implies that there is horizontal/angled/vertical hinging actions in the backswing. I cannot understand this biomechanical phenomenon. Does HK describe the biomechanics of backswing hinging actions? I can understand the followthrough hinging actions as being due to a variable degree of external humeral rotation happening at left shoulder socket level, and I can conceptualize the biomechanical process.

However, what is happening biomechanically if hinging actions are actually occurring during the backswing?
