For my understanding, the original MCAS design would stop and return the stab to the original position

I have never been clear about the software logic despite seeing the plots of what took place.
What I read: A "normal' MCAS activation would unwind the applied trim when AOA returned to within range - unless it was interrupted by pilot input.
In the broken AOA case it would never unwind since the unwind is triggered by AOA returning to normal.
