In the first try, I messed up. Don't worry about that. Now when I do it again, you can see I, tornado, e, q, r. Now look at the champion hot bar when I press R. You can see the first q stack to get the tornado, disappear. So let me explain, when this combo is done, you should have your first q stack back so you could hit one more q and get your tornado. But when pressing R, the first q stack disappears a milisecond after you press R, check the video what I mean. (Look at the Champion Hot Bar)
