The important thing is simply to acknowledge the assumption you're going from.
That's true, and I think most of us believe that the way we assume it would work is correct, and is the way we play it.
But the rules don't really say one way or the other, so we can't actually point to a rule that says to do it this way or that way. That also means there's room for FFG to decide to do it differently then we think it should work.
