The pressure would be spead out among them all, but you still need to suck to create that pressure. If you take a normal drag, it just takes a tiny bit from each of them. You could suck in more with the same force, or increase the force to get even more, so I guess it’s not like it’s doing nothing at all. But I realize now my first post was based on the premise of “why would you want to get more smoke, one cigarette is enough or too much”, which is the whole point of that thing, so maybe I’m the idiot for thinking too much about it.
