Default Question About 3-Battery/One Outboard Schematic

I’m presuming this is a three-bank system—-my question is regarding the battery switch on the right side of the schematic (connected to the “auxiliary” battery)

What is the reasoning behind this switch—-would it allow the “auxiliary” to be 100% isolated from the house battery and the start battery and if so, why would you want to do that?

I would like to add a battery to an existing two bank battery layout to power an electric windlass—-it appears that this schematic is how I should model the addition but I don’t quite understand that second switch—-is it necessary or just a suggested add-on?
