I would call it an unusual way of specifying the display to use.
Everything else seems to refer to the DISPLAY environment variable.

I can't tell if it would solve the problem because I haven't tried all
the options yet.  I usually don't run the X server listening to the
network, and I usually do not restart it.  I also do not know if the X
server needs to listen to the network to be able to use a remote Emacs
server --- after all, the client runs locally and should be able to use
the X server without it listening to the network.

It is relevent for 'emacsclient -nc'.

I want to be able to use the same Emacs session with multiple different
machines --- currently only two.

Why does anyone run an ssh server?
