Besides the fact of no sit which is just disappointing, also, from what I remember the cuff drag speed is very slow. So in that case, this just seems like a lazily performed sit.
In the case with the ledge biting? There is nothing against this, so why would you warn for it before looking into that? In fact, it is more against the person who instigated the 939's to get bitten in the first place.
However! A report comes with both sides of the story so.
