...then you ALWAYS point at/trace the Plane Line (1-L-6), no?
No.
Again, you do not 'point at' the Delivery Line when it is the derived Angle of Approach. You Cover it.
Here's why:
You already know that the Hitter using the Angle of Approach procedure no longer monitors the true Geometric Plane Line of 1-L-6. Instead, he monitors its derivative -- its Geometric (and Visual) Equivalent (2-J-3) -- the Angle of Approach.
Now, here's your missing piece: The Angle of Approach is not a new true Geometric Plane Line (whether 10-5-E or otherwise). The original Geometric Plane Line, while no longer monitored, remains vitally important as the 'Basic Basic' from which the Angle of Approach was derived. You can substitute the Geometric (Visual) Equivalent for the true Plane Line, but you can't substitue a new true Geometric Plane Line for the original! Remember, any new true Geometric Plane Line means a new Angle of Approach and that, obviously, would be a problem.
Summarizing, the Hitter monitors the Angle of Approach, the Geometric Visual Equivalent of the one and only true Geometric Plane Line. And 1-L-6 is satisfied by Covering this Geometric Equivalent with the Clubhead.
