Yes, you're right.  What you're seeing is the expected behavior.  The $$ 
macros don't get evaluated until a job is matched.  So when you do the 
submit, a log file with $$ unexpanded is created, which gets the submit 
event as you saw.  Then, once the job is matched, the $$ is expanded, 
which creates the second log file that gets the subsequent events.

If you don't need the +5, this will work, of course:

  log = cpubound_$(Cluster)_$(Process).log
