I think that it violates Freedom to Move rule as described in the official rules.
While official Pillbug rules do not clearly state that Pillbug can't violate Freedom to Move rule (they only mention Freedom to Move in the context of the special ability) they also do not say that Pillbug itself can violate this rule so I assume that this move is illegal.
I was watching through
