I think that a reverse-K position is simply a sign of a good backswing pivot action. One can shape all types of shots from that position.

A golfer can draw the ball slightly by swinging down the ball-target line and employing a horizontal hinging action. Or, to increase his draw power, he can perform the same action but have a plane line that is closed to the ball-target line while still having his clubface pointing at the target at address. I don't identify any necessary causal connection with the reverse-K posture at the end-backswing.
