With this not-local or not-remote, the X11 system just ignores communciation
from that direction. You can easy check that X11 needs the network interface
by disabling all network devices. That is, including the loopback network
device. You will see X11 is not working.
As far as I know, this faster communication by sockets and shared memory
that you inicate is the implementation of the local-loop network devices
(with IP address "127.0.0.1" and hostname "localhost").
