At the end of the episode, there are several scenes in which the "Wormhole X-Treme!" cast and crew break the fourth wall, discussing the fact that their show is a show within a show.
As the Show Runner for Wormhole X-Treme!, Martin would not have been ignored by the production crew like he is. Showrunners are the creative force behind television series, overseeing all aspects of production. They ensure the show's vision is executed properly, working closely with writers and directors. Thus Martin would actually be asked for his input quite frequently.
