Corrct, barit, and Brian is talking about reduced boost in cruise conditions. The point about torque reaction on TOGA is that it is going to be at high boost, and under those conditions reducing RPM means that torque reaction will go up. Or look at it this way. At max boost and max RPM if you pull the prop lever back to reduce RPM you are setting a coarser pitch. This will generate more torque drag on the prop. Of course, reducing RPM may force a reduction in ehp, but not necesarily on the engine's ability to produce torque. Where do you get max torque in your car?
We need more numbers!
