I don't know, maybe because the guy is made of fire and mountain ash is wood. It could be the same as Lydia but, as I stated, he shares a number of traits with the other shapeshifters and we have less examples of him dealing with a barrier. Having seen him do it once, the assumption would be that he too is not supernatural, after a few more examples we'll have a better idea.
