Whilst not commentating on the flight condition limits (a safety function), think of sitting in a slow moving car, putting it into fifth or sixth gear then pushing the accelerator down. Not much happens... In any case it's a free turbine, propeller not directly connected to the power turbine.
Bizarre that this sort of event can happen with an experienced trainer.
