No, Chris has it right....

There is no such thing as legacy addresses. There are addresses which
currently have legacy status, but, if those resources are returned,
transfered, or otherwise reregistered or freed, they are no longer
in a legacy status.

The part I think you are missing from Chris's point is that these are
legacy registrations. The resources themselves are only in a legacy
status so long as the current registration remains in effect.
