The superblock errors are detected but not corrected right away, because
next transaction commit will overvrite it.

Does scub report the errors repeatedly?

There are no other scrub errors reported, I guess there are also no
relevant messages in syslog. During transaction commit scrub is paused,
so it's not possible to verify a half-made superblock.
