Under this sequence of events:

1. Someone posts a question
2. I post an answer
3. OP comments on my answer
4. A third party adds a comment to my answer
5. I add a comment to my answer

Does the OP receive automatic notifications for either comment #4 or #5? The actual post in question is http://stackoverflow.com/questions/15713470/using-content-for-and-and-ajax-jquery-to-partially-update-webpage/15713497?noredirect=1#comment22319719_15713497. (I added a manual ping to the OP at the end, because I wasn't sure.)

The best source I could find for when automatic notifications occur I found at http://meta.stackoverflow.com/questions/125208/when-exactly-do-i-get-comment-notifications. If I'm reading this correctly, the OP will not get automatic notifications for either of those above events. Is this correct? That post is also over a year old, so I don't know if it's up-to-date with respect to how it works.

I apologize if this is a dupe, but finding details about exactly when automatic notifications occur is difficult.
