Does the voltage regulator automatically know what type of battery you are charging?
and if you had two different types of batteries that take different charges wouldn't that really screw things up??
I have to go stare at it and scratch my head for a while.

Dave, my stbd alternator knows the type of house battery bank b/c it's got an external, programmable Balmar regulator. My port alternator charging the start battery doesn't know with its internal dumb regulator.
I recabled my boat so that the alternator charge goes directly from the alternator to the respective battery. If I need to share the charge from one side to the other, I flip the switch on the combiner to tie the 2 banks together during charging.
