Because, in your example, the subjects were *not* the same - some
respondents have added spaces before the word "start":

These ones not only have a different subject, but also lack threading
information (In-Reply-To, References).  One thing that I think *is*
Gnus's fault is that thread gathering is done only against thread
roots - WIBNI orphans were also gathered against subthreads when the
subject changes?
