I was extending your example to add an unresolved msgid in message 2 but I typed 1 instead. The point being that when 1 is encountered it creates a dummy message based on subject and when 2 is encountered it will not match the previous dummy message but will create a new dummy message based on the msgid in the replyto.

Your analysis is correct and I agree with your conclusion. I was just being too pedantic in pointing out the cases that couldn't be resolved.
