It simply allows the starter battery to remain topped up when there is surplus energy in the domestic battery. This feature will NOT drain your domestic battery - it simply takes surplus. Once your alternator \/ engine turns on or you provide the BB with an ignition signal the BB reverts to normal charging of the leisure battery.
