Kelvin, I think you're right. Given the physical limitations involved, as well as time constraints, this discussion is largely theoretical. Most movement, if it possesses sufficient force to gain an advantage, is going to go beyond the vertical space belonging to the defense.

I can concoct a realistic scenario where there would be contact in the space defined by verticality...

The defenders arm are outside the vertical cylinder (horizontal) and are brought into the cylinder forcefully and subsequently make contact within the vertical space.
