Thats what I think they were getting at in '99, you might get an extra half amp out of the breaker if its on the output side...

The fans on the Victors are not there for looks! Those FET get HOT.
I have not measured it but at 100 amps, I would not be surprised if you dropped a half volt across each leg of the H-bridge -- that means you drop a full volt over both. Power = IV = 100Amp*1Volt = 100 Watts. This is a significant fraction of the power you are pounding through the motor.
Bottom line: I think that if you are tripping the 40 Amp breaker (or any of the breakers) you will get a noticeably longer time to trip if you put it on the motor side of the Victor. But as it is not legal any more, and, as Ken rightly pointed out, it can be a dangerous situation, don't do it.
