No, that's not correct. It has nothing to do with central managers at

-n is really meant for submitting to another schedd on the same machine,
or at least with the same view of the filesystem. condor_submit (or
condor_submit -n) tells the condor_schedd to create a new entry in the
job queue, and what files need to be copied into the spool directory -
but it doesn't actually send the files to the schedd.

-r also tells the schedd create a new entry in the job queue for the
new job, and what files are needed - but then sends the files needed 
to the schedd, so you don't need a shared filesystem between the two of
them (it's actually a lot smarter than that - it creates a job on the remote
schedd with that job in the 'HOLD' state, transfers the files over, and then
releases the job, so we can recover from crashes)
