If i understood the description correctly just pulling would not stop the trim in the case of MCAS.
The stab trim switch would stop it and it would start again after 5 seconds.

They had been flying more or less stable at around 5000 ft for quite a while (7 minutes) before they plummeted so the sudden pitch down is a puzzle.

It's hard to speculate any further without additional info but anyway:
Maybe the fault was intermittent?
Maybe they believed the stick shaker that they were stalled when they started the last pitch down?
Then when trying to pull up they could not because of the trim?
