Not sure offhand, and I don't have any experience with xfs on crypto block devices...
For starters, how about xfs_db -r /dev/loop2, then:
xfs_db> sb 0 xfs_db> p xfs_db> sb 1 xfs_db> p ...
etc, to see how the various superblocks differ & why repair doesn't think they match (note, there will normally be some variation in a few fields, as not all superblocks are fully filled out at mkfs time... )
