and where is it documented.

Not sure where it is documented (Q/A on the beta forums is the closest that I know of), but there is an explicit pulse/message sent out over PWM and CAN to disable all controllers as soon as the system enters the brownout state. The goal of this (whether you agree with it or not) is to save the rest of the system from browning out.
