Thank you for reply.

Oh, nice googling.

That may be - if 勿* was a verb it would probably be that way. I couldn't find any relevant "勿* #verb" in Jisho and that 勿れ ends with れ is sorta interesting too (it's maked as a "particle", so I guess that can pass). But this gives it some basis why the author could have used it this way.
