I think you're not considering the first album with an actual track called Mobius. Your thinking of the opening cut on Orbital II (the brown album). That one is the one where the "where time becomes a loop" becomes fun. The Mobius track is the one where "whatever happens, will happen again" is also included. Sorry, but I will have to deduct Orbital fanboi points, and you will lose your next turn

Edit: But as to the why, it's fun. Just like the "input/output translation" trickery.
