Not necessarily. Any individual user can only upvote once, but can leave many comments. So if any sort of conversation happens where the same users are posting multiple comments, that effectively ends up penalizing the overall post. I understand the idea behind it, but I don't think it works very well in practice. It works sometimes, but I've also seen it kill plenty of posts that were totally fine.
