There is nothing we can do here. YouTube starts playing the next video, without navigating to the page of that video, while in fullscreen. So no new player is initialized with flashvars. Instead the existing player is told via JavaScript which video and which ads to show. Unlike with flashvars given in the HTML, there is no way to manipulate this configuration.
