Not really.  That flag means if there isn't a server running, start
one.  It doesn't start another Jack server if one is already running.
So yes, it is Jack "automagically" knowing whether it should run a
server or not.  It doesn't need to be running anything beforehand
though - the check is made when the software registers a new client.

Yes, that's the fun of this with the launch behaviour hard-wired in at
compile time.  I now remember that the bit that confused me was why
the settings file created by QJackCtl was being ignored - because I
wasn't using dbus in normal use.

Yes, and (kind of) yes. ;-)
