I'm not sure I am exactly following your descriptions. However one
consideration that may have Aeroelectric Bob running the B lead
through the starter contactor, is the battery can be used as something
of a filter for any alternater noise if the current goes to the
battery then the buss, as opposed to going directly to the buss from
the alternator.

That's what he does it for, to reduce the noise from the B lead, from
what I gathered reading his book.
