It was actually mentioned in an interview with the actor playing Dorium that Steven wrote that scene as a deliberate 'extra' while they were filming the real scenes. I think in a way it was created to explain why Dorium describes the Headless Monks as old customers, and his comments on the security software in the episode - but they're not really required in order to enjoy the episode.
