It's like you read until that point, but then didn't read the justification for why it makes sense to care about frames during the animation, the author does outline a bunch of reasons why it should make sense during the entire thing.

Maybe I've just spent too many years as a pixel-perfect chasing frontend developer, but things can look very janky if they jump out of place during animations, compared to where they are before/after.

My comment starts with "After reading this blog post"; of course I read it, but it left me totally unconvinced, especially because the author doesn’t bother showing good examples: he criticizes these and then leave you with a random raccoon animation and that’s all. For example, I don’t understand what’s wrong with the Youtube animation; it looks perfectly fine to me.
