Wait, allow me a minute to understand your point so I can correct the drawing.

Are you suggesting that anywhere on the circle the ball is struck before Low Point, that the shaft needs to be at right angles to a line ............

I mean, we have added "Hook-face" to divert the ball from its true tangential path. Besides, anytime the primary lever is Turned, the shaft would not be at right angles ........

Help me out here. The bottom drawing shows that the clubshaft is not at right angles until Low Point because the Left Wrist is uncocking and the Primary Lever has not become Vertical.

The Top drawing represents a shaft-only orbiting around a circle and because its center of rotation is the center of the circle, the tangent will always be at right angles to it.

I do believe HK said the primary lever is never out of line. I see the Dual Centers of 2-D-0 makes the hinge as one of the centers . So the tangent at any point on the circle would be correct. ????

The second drawing would not occur fo simultaneous release and angled hinge. And it will not occur with my understand of sequential release, but that is another problem for later.??
