Well, that makes perfect sense. HK assumes the reader has been with him all along doing the research. You've got to have inside knowledge to explain the "Reverse Loft" sentence. I've been thinking about that for many years and I've never been as satisfied with an answer as that.

Muchas gracias.

I had the great benefit of Homer's own guidance in this question. That is why I actually bought the 'negative loft' putter and was able to correctly demonstrate its use to the students of my golf schools in the early 80s.

Absent my first-hand knowledge that he was referring to the True Swinger, the key is found when he states the alternative procedure to the negative loft putter: "Else manipulate the Clubface per 7-2".

That paragraph (7-2 / Grip Types) details the key alignments and relationships that must be established at Fix in order to establish a Vertical Left Wrist at Impact (versus Low Point). These include the in-line Left Arm and Club, the Flat, Level and Vertical Left Wrist, the Right Forearm, Pressure Points, Ball Location, Plane Line, Knee Bend and Waist Bend.

Note that all the "Clubface manipulation" of the Manipulated Hands Swinger (as opposed to the True Swinger) is done at Fix (Section Two of the Stroke) and long before the Clubhead leaves the back of the Ball in Start Up (Section Four of the Stroke).
