The perils of multiverse travel

The show: Family Guy
The episode: "Road to the Multiverse," first aired on FOX this past Sunday.
What happened: Stewie takes Brian to see a parallel universe in which religion never existed on Earth, allowing technology to develop at a much faster rate. When Stewie tries to return them to their home universe, the device instead sends them to another parallel universe. Thus, Brian and Stewie spend a great part of the episode going through several random universes, such as a universe drawn by Disney, a universe in which everyone has two heads, etc. When they arrive in a universe in which dogs own humans as pets, Brian smashes the device because he wants to stay in that universe. The dog Stewie from that universe recognizes his parallel Stewie, and, in a plot twist redolent of Sliders, he explains that he has created a better version of multiverse sliding and can return to his proper universe with precision.
What doesn't quite make sense: Alright, we accept the premise that you can slide between parallel worlds. (Note that the episode was careful not to use the word "world"). But why is it that in some worlds, Brian and Stewie were reconstituted to match that universe, but not in others? When Brian and Stewie go to the universe that is Washington Post political cartoon, their appearance changes to match, with Brian getting a button with "LIBERAL" written on it and Stewie a New Year baby sash; and when they go to the universe drawn by Disney, Stewie's head shape is normalized to Disney standards and Brian becomes less anthropomorphic. But when Brian and Stewie go to the universe in which everyone has two heads, one happy, one sad, neither Brian nor Stewie sprout a second head; nor do they get redrawn in the Flintstones style when they visit the Flintstones universe. Is there some rule besides script necessity for reconstitution or lack thereof?
