Hi guy! I'm the one who made that pattern. You are correct that it is not optimal play. What it is is a lot more interesting than what it isn't: it's a clear demonstration that survival is trivialized with the "7-bag" random generator. Tetris games used to be enjoyable to play for survival, and that is lost in recent games. Regarding extreme speeds, you make a good observation. This pattern cannot cope with pieces spawning on the floor. That said, I 100% believe it is possible to construct such a solution. But the existing pattern stands as something to remind people that Tetris used to be fun without extreme speeds or awareness of scoring gimmicks.
