GM Gen 3 platform Engine Drivetrain Abuse vs Trans Abuse Mode

I have seen various Gen 3 videos where they have us us disable "Abuse" under either the Engine or the Trans sections or even in both places, but I am still confused on how the Engine Torque Management Drivetrain Abuse differs from the one under Trans Torque Management called Abuse Mode, could you elaborate on those please. On my 2001 GMC Sierra 4.8L one is set to 1,600 RPM and the other to 1,200 RPM for example.
