Correct. Also note that the concept of a single RIR managing each
/8 only applies under certain circumstances; there are many cases=20
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=20
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.
