I think the attributes are independent.  Whether or not to perform an NPRO
probably depends on why, and for how long, the Printer is being shut down.  If
it's just for some quick maintenance, an operator might want to do Shutdown with
"when"='now', "non-process-run-out"='false', "synchronize"='true' in order to be
ready to resume quickly after the maintenance.  If the printer is being taken
offline indefinitely, an operator might want to do Shutdown with
"when"='after-all' and "non-process-run-out"='true' ("synchronize" is don't-care
when "when"=='after-all'), in order to finish up and flush any outstanding jobs
before shutting down.
