As with all catchphrases, it's a type of truism. Not that that's bad per se, just that it's better to takeaway that by going slow, you'll be better at identifying, planning, and avoiding "blunders". The tradeoff is: you're going slow. (c.f. Uvalde) There's a kind of corollary on how to get fast from music: you practice as slow as you can perfectly play the etude, then go one step faster until that is perfectly played.
