The pilots did the best they could. They increased airspeed to have at least some lift despite the excessive mistrim, and they turned electric trim back on because in the 737-NG autotrim stops when the yoke is pulled. No one told them about MCAS and how it behaves different from the model that they knew.

I think there is a lot of misinformation in your post.

The pilots didn't follow the airspeed unreliable procedure, and oversped the aircraft. Maybe it's the best they could do, but definitely not what they were expected (and trained) to do.

Electric trim is not turned off "when the yoke is pulled" - it's momentarily turned off when electric trim thumb switches on the yoke are pressed.

And they switched it back on because they couldn't manually re-trim due to very high speed that the plane was travelling at that point.

BTW the airplane was a 737 Max, not 737-NG.

I believe the parent's point was that they did what would have made sense in the NG, not realizing it wouldn't have the same result in a Max.
