Correct.  Also note that the concept of a single RIR managing each
/8 only applies under certain circumstances; there are many cases 
where multiple RIR's manage resources under a given block and work
together to make sure that things like in-addr (and RPKI) function.

This could easily be the case with this particular address block at 
some future time, depending on the state of global return policy.

This has already happened in many cases; address blocks previously
held by US DoD, BBN, Stanford were returned, held for a period,
and then reissued.
