Your assumption was correct...Collocate will attempt to place every new node 
onto a different scratch tape.  If the tapepool is at max it will then use 
existing tapes defined within the pool.

No.....

With collocate you put a maximum of 1 node on 1 tape, so A is not possible,
the 5th node does not have a scratchtape to use.
With collocate every node have's a own set of tape(s), so you need less
mounts when you restore, so the restores are faster. However, the migration
and reclamation takes more time and it takes more tapes. With 12 nodes,
you've got at leased 12 tapes 'filling'.
