No, changing the subject line doesn't make a new discussion thread. As
long as you use "reply", your post will include an "In-Reply-To:"
header with a reference to the post you are supposedly replying to, and
most "threading" clients will rely on this information rather than the
subject line. You really need to use "new" or "compose" to start a new
thread.

Yup, I agree with all you said above.
