I don't think "watching" threads works

[Timurama]

I assumed that this a subscription button that would notify me about every new post in a thread but instead it notifies me selectively on some of the posts, I though I'd 'subscribe' to those manga pages uploaders make and post new stuff periodically, and what do you know? no notifications came when that happens, example of a thread I'm talking about.
I mean, I'm kind of disappointment that there is no reliable way to track content on this site, not counting direct replies to me, what i get bell notification for after clicking 'watch' button are some of the comments in an extensive discussion thread, example. Despite having daily posts, having subscribed to this thread i only received notifications about 2 times, and that was already a week ago. Edit: well that thread just got a new post and this time I got a notification, I really don't understand why it ignored almost every other post and notified about that one, was it because I opened that thread recently?
So i don't even know what this functionality supposed to do at this point and what the logic is, maybe I'm placing different expectations on it, and I would like it if someone cleared out this confusion, if it's no trouble.
