No, it really does not, especially across reboots.  We found that the
only way to actually preserve your devices was to have a /dev/multiseat
directory controlled by a daemon which gets kicked by hotplug events,
and then uses some hand-wavey heuristics to try to work out which mouse
it is.

People aren't very good with using all the identifier fields in the
HID spec.  In fact, they don't bother at all, because it's much
cheaper.
