Did you make multiple posts in a row?
Maybe due to my level, I am restricted to make multiple posts together. So there is always some minutes gap. But if you mean replying 1 post and then replying next again then yes but that's because I wanted to reply to both.
Reply in one post like Bitcoin_Arena explained. Because:
32. Posting multiple posts in a row (excluding bumps and reserved posts by the thread starter) is not allowed.
