Yeah, it really seems like this article is describing the default. It's good to accept and understand that writing stuff into notes doesn't ever imply you'll read it again.
That doesn't mean that if you make the effort to read the notes again you won't get value out of them. It's just saying "You realize you aren't on track to read any of this ever again right?"
I think they're different kinds of notes you're talking about. If you're doing applied study to learn something, sure. But most notes are not that directed or profound; it's more like "I liked this song on the radio; let me check out this artist whenever I have time." If you haven't bothered in a month you probably aren't ever going to.
For directed study, though, I find making the notes if oten more helpful than referring to them again.
I find this the case, but I've also found anomalies where I one day watch a movie that's been in my watchlist for years. One day something that seems stale just seems new again. Not sure why.
