If you enjoy talking about parallel universes, I highly, highly recommend watching the SM64 1-Key speedrun [1] and then Bismuth's explainer [2]. It's a truly amazing technical achievement based in large part in pannenkoek2012's research.
Lots of bugs have specific names. It would be crazy not to name any.
Changing your position so that you're in the same spot but you're also in a completely different location, all at once. I think the term fits pretty well.
The PU term fits very well. It makes sense. It just is also funny knowing what is going on behind the scenes and seeing their explanations and rationaliations.
It reminds me of outsider art. Someone comes along and documents what they find with no exposure to the community or its conventions.
I'd bet that almost anyone that has ever managed to make this trick work could have told you the coordinate is wrapping. What rationalizations are happening?
I think if they weren't rationalizing they would explain the concept as is - its a wrapping coordinate. I do agree they understand what is happening low-level and that it is a wrapping coordinate. They still choose to use this parallel universe explaination for ease of understanding and explainability to outsiders. A rationalization is just "the action of attempting to explain or justify behavior or an attitude with logical reasons, even if these are not appropriate" which sounds exactly what the PU explaination is. There is no derogatory insinuation or anything involved here.
But I do disagree about rationalization. If something is a deliberately oversimplified explanatory tool, that's not a rationalization by my understanding of the word.
