Not sure how serious this is, but to give a little more context, the standard methods involve memorizing 57 algorithms for OLL (“orientation” of the last layer—getting all the yellow bits on the top face) and 21 algorithms for PLL (permutation of the last layer—fixing the sides of all the top cubies). Breaking it down into two steps reduces the amount of memorization quite a bit—and also makes recognition of the cube state for what algorithm to use much faster. The guy said on reddit that doing this memorization didn’t help his times: his average is around 15 seconds, which is nowhere near record-breaking these days. The world record average-of-three is sub-5 and a friend of mine’s average is around 11, for context. I would guess that recognition takes him substantially longer than most champion speedcubers, and that’s not helping. So that’s probably why this guy is the first to do it. Not much incentive to other than to be able to say you did!
