That's incorrect.
The math for audio gain control and MIDI gain control are separate and different.
The fader controls whatever types of signals are presented to it. If there is audio, it will do audio gain control; if there is MIDI, it will alter the velocity values of MIDI note on messages; if both are present, it will do both.
It will never scale a MIDI note on velocity value to an illegal level.
