Lets look at two plays that are slightly different from the original play but where the principal of verticality is the applicable rule.
Play 1: A1 has control of the ball. A1 is standing and not dribbling. A1 is being guarded by B1 from behind. A1 bends over and B1 bends over A1's back. A1 then straightens back up and there is contact between A1 and B1. Foul on B1.
Play 2: A1 has control of the ball. A1 is standing and not dribbling. A1 is being guarded by B1 from behind. A1 has not yet established a pivot foot. A1 drops the ball. A1 steps forward with his/her left foot (his/her rigth foot is now his/her piviot foot) and bends over to pick-up the ball. B1 bends over A1. A1 regains control of the ball and moves his/her left foot back near his/her right foot while resuming a straight up (not bending over anymore) position. There is contact between A1 and B1. Foul on B1.
In both plays B1 has infringed upon A1's cylinder of verticality.
In the original play B1 has infringed upon A1's cylinder of verticality by straddling A1's right leg. Even though A1 is in a somewhat off-balance position, A1 has the right to his/her cylinder of verticality.

In neither of your "test cases" is the foot of A1 out of the cylinder of the rest of A1's body. That's a crucial distinction, I think. I'm pretty sure that the last time we discussed this, we agreed that the verticality cylinder went up and down from the pelvis. If B1 makes contact, I think it's still a push on B1, but A1 doesn't get that space back once he/she has surrendered it.

A player's cylinder of verticaltiy starts at the court where his/her feet are touching the floor and goes to the ceiling. It does not start at his/her pelvis.
