Send/receive of subvolume changes, efficient incremental filesystem mirroring and backup
This is explicitly talking about a different feature that can incrementally sending changes to the filesystem to another filesystem as a backup. Not at all about how snapshots work.
My interpretation was that since send/receive foots on snapshots, those would be related, but I guess, the incremental backup is actually a separate thing.
Some articles online call them “incremental snapshots” as well, which is where I might’ve gotten that initially, but I agree that on a logical level, they’re not that, even if they’re similarly space-saving.
You missed an important part of that quote:

Hmm, yeah, I guess I’m wrong there.
