The emergency start switch is often used to start the generator. The coach battery(s) can get run down and you may want to use 120 volts for something. Either way, the switch connects the 2 banks of batteries.
The engine alternator would charge the coach batteries faster, but it would burn more gas and be noisier.
On my motorhome, the emergency start switch isn't very helpful for starting the generator unless one has a helper or somewhere around a fifteen foot armspan. What does work when alone is to start the main engine (which also activates the coupling relay) and then walking back to start the generator. Even better, of course, is to avoid letting the house battery get so low that the generator cannot be started.
