Is the B737 similar, and what about the dash-800 MAXI?

Trouble is that, when the a/c is already pointing downwards at a very low height, releasing the yoke to unload the elevators is not an option...
That is true. The pilot would have to know exactly what he is doing and act real fast and hope he could pull out in time.
