Consider, === as the hip plane and / as the clubshaft plane and then explain how the horizontal plane, rotary, shifting of the former can initiate the inclined plane downward motion of the latter.

Burner,

You may have difficulty finding a rear-wheel-drive car that you would want to buy.

The rotation of the lower body does 2 things. One, it moves the tailbone closer to the target at impatc than at address (with open hips). This allows continuation of axis tilting and a longer straight line delivery path than otherwise possible. Two, drives torso rotation. The body has to bend to accomodate the rotation of the hips, maintain a steady head and allow translation of lower body turn into torso rotation. This provides momentum to be transferred (in a more correct plane) to the club via throwout during release.
