As you've discovered, the issue is that HTCondor will match a job to a 
machine in several places:  First, in the negotiator, then in the 
schedd, and finally in the startd.  The SubmitterUserResourcesInUse 
attribute is only available in the negotiator, so the job would match 
there, but not anywhere else, and thus never run.

If your ultimate goal is to limit the number of jobs running per user, 
you may want to look at accounting group quotas, which can usually 
accomplish the same goal.
