Considering Jinchuriki and Edo Tensei die when the thing possessing them is ripped out, Kakashi collapsing is a very mild reaction.

Oh my bad he did end it, but considering how depleted obito was after opening the portals to rescue sasuke, I don't think kakashi had enough chakra left to maintain his use of the mangekyos.
