All the mail clients that I know of, attempt to intelligently use many fields
to determine threading. If there is a clear reply-to-message-id, then
obviously it wins. But sometimes that's not present, so it looks at other
fields, including the subject.
I can say this much:
I have posted this exact same topic on multiple mailing lists, and it would
seem, that some or all of them strip the message id's (or something) or simply,
the message id matching is sufficient but not necessary to be considered a
thread, or something... because I have threads which are actually separate
from each other on separate mailing lists being displayed as if they were the
same thread, just because the subject almost matches.
