To give your elevators a chance against that massive stabilizer. If you keep the thrust in there, you will continue to speed up and at some point the thrust pitch couple is going to become irrelevant as the aircraft starts going downhill. At high speed going towards the ground with full nose down trim, you might as well not have elevators. Only thing you can do is trim for your life. And depending on how close the ground is, results not guaranteed.
Much better to reduce thrust ahead of time. It's going to want to go downhill, but you should have enough elevator authority to keep it from doing so despite being mad out of trim. At the same time you use electric trim to lighten the pull and if you reach the conclusion that something is wrong with the automatic trimming (which conclusion you probably SHOULD have reached by now), then you cut it off with the switches. You are now in a more or less stabilized state.
