It's a two-stage operation that brings the aux alternator
on line AFTER closing the auxillary feed relay
between the battery and AUX bus.

It doesn't. Raise the switch one notch and you've
got the aux bus hot without powering the aux alternator
field. See chapter in the 'Connection on special switch
functions.
