It is from the submitter. I think it is intended as a submission statement.

That’s the first time I’ve seen/noticed that. I think it makes me feel better?

Not sure what you were feeling bad about, but it’s also directly from the readme, so OP just saw something cool on GitHub and posted it along with a comment with the project’s own description, which is pretty standard on HN (I think, that’s how I’ve done it at least).
