That was my take on things. The idea is to protect the alternator from burning up by limiting the demand on it. Both systems accomplish this. I went with the LBIM.
Properly wired it is off line unless the ignition is on. It limits the draw on the alternator by cycling on and off as you mentioned. It also can provide the emergency jump from the coach battery if the chassis battery is too weak to start the engine.
There is probably not a real issue unless there is a high draw of current from the coach batteries. In my discussions with Battleborn, I understood that to be most likely with three or more coach batteries but being cautious, I opted for the LBIM with my two batteries.
So far, with the 400 watts of solar, I haven't put much of a test to the batteries and that included some camping in the redwoods with very little direct sunlight. Consequently, I haven't put much of a load on the alternator.
