I will take a look at the definitions this evening. I notice you use the term "preselected" which would indicate to me the alignment is set at setup or address and is not altered during the swing.
You are correct, Tball. You determine the Hinge Action during Impact Fix -- Section 8-2 of the Stroke. Then, with the Left Wrist in its Flat, Level and Vertical Impact condition, you align the Clubface as dictated by that selected Hinge Action: Slightly Open (Horizontal Hinge Action); Slightly Closed (Angled Hinge Action); or Square (Vertical Hinge Action).
Also, at the Top (8-6), you monitor the alignments of Section 6 of 12-3-0. This includes the Delivery Line Roll Prep, i.e., making sure you are prepared to execute the On Line Roll of the #3 Accumulator -- with its Hinge Action and its inseparable Rhythm -- through Impact. This should be practiced with the Clubshaft tracking back and through on the edge of a low bench as you execute the Hand Motions described in 2-G and 7-10. This will teach you to Trace a Straight Plane Line -- not a 'Bent' one -- with your Right Forearm (to guide the Clubhead through Impact) while simultaneously executing the correct Hinge Motion with your Left Hand (to control the Clubface).
