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@xxxxxxxxxx>

    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
