I don’t know of any good way to signal or display that a comment has multiple parents, and thus “merges” two threads. There are a number of boards and discussion systems where a moderator closes a thread (either making it read-only or just deleting unwanted further follow-ups) to keep noise down.
Note that this is a problem in verbal debates as well—there are always sub-points that spawn further sub-points, and even if you notice a merge point, it’s hard to remember that you did.
