Mike.. I think it makes sense to me at least for the finger to be Hooked for swinger..

Due to the Pitch elbow. and Karate chop... the Hook trigger finger places the PP 3 directly behind the Plane of action ... or the ARC of Circular motion.

While for a Hitter , the right hand is relatively more Perpendicular to the plane of action. also caused the PUNCH elbow and the "primary lever assembly" ... if assembled together. Put the pp3 behind the Angle of Thrust ..

Like a Jigsaw puzzle.. One puzzle fit to another puzzle..and it all made more and more sense.

Study 10-18 and 10-2. The shape of the finger has nothing to do with how or who uses the Lag Pressure of pp#3. It is the Action of the Left wrist that is being used in the stroke.

It is not the positions you want to create they are useful but how they form with proper alignments- not the same thing. Horse and cart kind of thing.
I would concentrate of using the components Homer listed in 10-1-0 and 10-2-0, add the correct Action and forget about what position something needs to be in. The alignments work. You will find the puzzle fits fine.
