All I can remember is that back in the dark ages, when we were first
messing around with "personal condors" and trying to make things
work-able, we found that people were regularly confused and ran into
trouble if everything after the @ wasn't a fqdn.
Furthermore, there is logic in The Tool(tm) that resolves hostnames in
the command-line args to be able to locate the daemon you're trying to
talk to. Actually, the logic is probably in the Daemon object itself.
So, if you say:
"condor_reschedule wright@tonic"
the tool knows enough to find the right schedd. That depends on it
really being a fqdn...
