Swinging elbows or not

How do you have a vertical plane when you are not vertical?

A1 WAS in an unnatural position legs spread and leaning back and is not entitled to the space above and outstretched leg.

This is no different than a player attempting to draw a charge or set a screen by sticking out an arm or leg.

They have protection above their vertical torso extended and not some protective bubble surrounding their entire body, regardless of having outstretched limbs or a diagonal orientation.

Vertical means vertical.
