You thought perhaps they commented a list of random unrelated HN submissions?

The links are all just https://news.ycombinator.com/item?id=########. It's obvious they refer to some content on HN, but it could be comments, replies to comments, etc.

By adding a small bit of human text, the human doesn't have to ponder the list and wonder what they will get if they click a link.

And if there were human text, someone arriving by way of the parent comment link would have an easy time understanding the context without having to scan a lot of characters and make assumptions.
