Something had to be happening in the period while electric trim was disabled, we don't know what since the CVR transcript has not been released.
The implication of your post is that the 737 pilot is happy to accept a significantly out of trim aircraft.
What was being assumed is that an experienced pilot would not let the automatics whatever they were put the trim where they didn't want it.- so when the Stab Trim cutout occurred there would not be a large out of trim condition to wind back.

There is also a lot of confusion between 'manual trim' with the column electric trim switch and manual trim with the non-powered trim wheel.
