I don't think this is related to concurrency. That is unless you are
trying to run the same job on the same client at the same time but at
different levels.

No you are correct. Simultaneous jobs allow multiple jobs to use the
same storage device at the same time. Provided that only 1 pool is
involved because a single (non autochanger) storage device can only
load 1 volume at a time.
