I wasn't aware this was being done, but your guess was correct. The
WARN_ONCE state is getting cleared between each test in xfstests, with
the rationale (which IMO is quite reasonable) why this done in the
xfstests commit descrition:
commit c67ea2347454aebbe8eb6e825e9314d099b683da
Author: Lukas Czerner <lczerner@redhat.com>
Date: Wed Jul 15 13:42:19 2020 +0200
check: clear WARN_ONCE state before each test
clear WARN_ONCE state before each test to allow a potential problem
to be reported for each test
