I don't know specifics, but I do know that Mail uses more header criteria to group messages by conversation than by thread. I would imagine it takes the domain-related headers into account, but this is just a semi-educated guess. You can, for example, change the subject line in the middle of a thread, and it is still grouped into the original conversation.
