The exact message is "Notify me when new comments are posted" and there are two options beneath it? 1) "All comments". 2) "Replies to my comment". Is that it?
Argh. Only anonymous users are supposed to see that. So assuming you're seeing this when you're logged in, it's a bug. I logged in with a test user and I can't see it there so this may be a side effect of your super powers. Anyhow, you don't have to check it. Authenticated users are always auto-subscribed to forum topics they post to. If I'm not mistaken you've subscribed to the forum content type so you're getting notifications for everything anyways. But I'll look into it.
Forum comments notifications: you shouldn't be seeing that

Just ignore it for now.
