I totally agree , no need for a headache you got it right.

For flatter Plane Angles there is more In and less Up in the Three Dimensional orbit (forwards, up and in post low point). So Elbow Plane does have more Left (In) to it than higher plane angles. But to do this and swing left in a non aligned to the base line of the Inclined Plane manner is to risk what Homer termed "Bending the Plane Line" as the clubhead orbit goes three dimensional . .. non planar, with all its loss in precision and power.

Plane shifting can and should have no effect on the Base Line , Plane Line. 1-L-18. In this way the clubhead orbit stays 2 dimensional and the plane is not "bent".

Heres a plane board , but one that shifts angles (double shift represented here) while maintaining its aligned to the plane line relationship.

Keep preaching O.B.!!!!!
