It's because it's one of the attacks that successfully hits through a guard break. It deals CRAZY stamina damage, so something like a Grass Crest Shield is worth nothing for blocking.

Certain strong attacks seem to be able to do that, it might be worth testing. Smaller weapons (apart from Maces) seem to generally be incapable of striking an opponent through a guard break.
