Yes they do.
:o)

I think what kevin was getting at, and what you were asking about, is:

If you set the MPX=1 in the schedule, regardless of the MPX level of the
STU, the "lowest" number is the one that is observed.

F'rinstance, you've got 2 jobs running....schedule and STU MPX=4, so
effectively, you could start two more jobs and they would start
streaming to the same tape.

If you start a single job in another policy with MPX=1, even though
there are 2 streams "available" on that drive, the MPX=1 job will wait
untill it can have sole use of the drive before it starts, as the sched
limits MPX=1.
