This is my understanding also, based on the schematic posted before:

737MAX Stab Trim architecture


When MCAS is engaged, control column "extreme deflection" towards pull will NOT disable MCAS trim down, but it will NOT disable your thumb switch trim up either, so you still win.

In other words, this battle will not be affected by too much pull.
