You're not doing anything wrong, but RESYNC may indeed not be doing what
you want. If that's the case, send us feedback through the official
channels.
The LABEL operand on the FLASHCOPY command is provided by z/VM as a matter
of convenience, and is likely most useful for non-persistent (or at least
non-incremental) relationships. But, it is not subject to the same
persistence as the FlashCopy relationship itself, which is managed by the
DASD subsystem. As a result, the RESYNC command you're doing is noting
that the labels on AAA and BBB are different and thus should also be
resynchronized.
