This looks it's describing the same technique as the last example in https://emilkowal.ski/ui/you-dont-need-animations https://emilkowal.ski/ui/you-dont-need-animations (and that whole post is worth a read, I think, if you found this interesting). It's such a small detail that I wouldn't have otherwise noticed (because I don't build animations, so it doesn't cross my mind), but now that I know about it, I think about it all the time.
