I don't know how -stable maintainers handle more than one Fixes:.  One
of the above was released in 6.3, the other in 6.4.  What are they to
do?

My opinion: developers should use Fixes: as a request to -stable
maintainers to target a particular kernel version (and later).

If the developers indeed want to fix both kernel versions then wouldn't
two patches be best?
