Sorry to call you on this one, but you CAN have multiple retentions on
one tape.  Under your Master Server Properties / MEDIA there is a "Allow
Multiple Retentions Per Media" check box which I am forced to use.  I've
got 4 sites without robots that use Netbackup to write 2 week, 3 month
and 1 year retention data to and without this I'd be up the creek!

I'm not sure who shelled out the big bucks for Netbackup for a site with
no robot, but that's another debate entirely! =P

Agreed...but mixed retentions has nothing to do with multiple volume
pools.
You can have 10 different retentions and only 1 volume pool, and you
will not get two different retentions written to the same media.
A single volume pool does not equal mixed retention on one media.

But each tape has a different retention.
