I think you may need to watch the video again, the only cars entering in the right lane should be those cars turning right at the next exit, if you're going straight or turning left you should enter from the left and get in the center roundabout lane. Exiting from the center lane what you're supposed to do, just make sure you watch out for any cars on your right. It ain't rocket science but that doesn't mean you won't come across someone who doesn't know what they are supposed to do.
