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.
Nuke - As long as you have a pressure point 3 in the right place, the shape of the right index finger around the shaft doesn't matter in hitting or swinging. It can be helpful to have it hooked if you prefer a lagging takeaway.
As Mike mentioned, Lynn explains pp3 loading very well in the gallery.
