I think I've seen this before... I think the idea is, some transitions between particles (decay paths etc) don't work. The structure of the paths that are allowed match up with codes that are "correct" in an ECC algorithm. In ECC, if you get an invalid code, you can correct it to a valid code. I can't think what the physical analog would be - if a particular kind of transition happens, it gets "corrected" by the Universe to a valid one?
