Yoda - if you are arguing that the general tilt of the lumbar spine is towards the right (away from the target) then I agree with you 100%. That's my mental picture of what happens to the human spine during the backswing pivot action - the junction of the lumbar spine and pelvic sacrum moves slightly leftwards as the right buttocks moves backwards/leftwards, but the frontal spine orientation becomes rightwards oriented so that the entire spine develops a rightwards tilt away from the target.

Here is a photo image of Ben Hogan at the end-backswing position - from the front view. He has a reverse-K look, because although his right thigh is oriented to the left, his spine and upper torso is oriented to the right due to the increased rightwards tilt of the spine that occurs secondary to the movement of the right buttocks leftwards/backwards (that produces a reorientation of the spine to the right).
