Is this supposed to happen?

KILZ flashes madly around the arena.
KILZ drives towards TRAFALGAR LAW and seeks to destroy him.
KILZ tries to knock TRAFALGAR LAW down with the force of the blow! (-Barreling Attack-)

>> TRAFALGAR LAW SWITCHES TO STRATEGY 4

KILZ jumps and skips around his adversary.
KILZ attacks in a frenzy.

So we can see the barreling attack hit but there is no damage which i guess happens now, there is no resist message which i have seen in other fights, but yet Trafalgar Law was not knocked down.
