Forum Watches - notifications are not working as expected

• Error

We've been using the forum notifications ("email this address for any postings to this forum"), but would like to start exercising more fine-grained control over these notifications. The "Watch" concept appears to be exactly what we need, but some of the behavior I am seeing is confusing and may be contradictory to the docs.

According to the Tiki Docs on Watches, there are three kinds associated with forums:

1. A Watch for a Forum. Any new topic/thread posted should notify this user. I'm assuming it is represented by forum_post_topic associated with forum id within the Mail Notifications listing.

2. A Watch on a Forum Topic. Any new posts to that specific Topic/thread will notify user. Assuming forum_post_thread, associated with the topic's ID.

3. A Watch on Forum Topics & Threads. Any postings within that forum, be it Thread or Replies, will be sent. Assuming forum_post_topic_and_thread associated with the forum ID.

The problem I'm seeing:
* Some people have established forum_post_topic and forum_post_topic_and_thread on a specific forum
* Different user has posted to a forum, and he is set to watch that topic/thread (from_post_thread).
* People respond to his post
* The only people receiving notifications are a union between forum_post_topic and forum_post_topic_and_thread.
* I expected the notifications to be a union of the original author (forum_post_thread, on that thread) and forum_post_topic_and_thread (on that forum).
* In other words, the original author asked to watch his topic, but he received no notifications of posts/responses. Additionally, people who have asserted forum_post_topic on that forum are receiving updates, when I would expect they only receive notifications of his original topic post, not the subsequent responses.

Thanks,
Josh
