Your comment probably got split off because it was not a reply to the OP's comment, it was a general commentary on the topic.

Hmmm ... I haven't seen much of that happening on HN. People respond to the top comment all the time. Also, it was a direct question to the person who posted the top comment, not a commentary.

Well, your question is really vague (I don't understand what you're asking), and it's one sentence, followed by a three-paragraph monologue.

Have a great day!
