If there is a stop but no plane change with the same flight number, the entire flight counts as one segment, correct?
You have it just about right. For a flight with a stop it doesn't matter if there is a plane change. If it is the same flight number then it is one segment regardless of if you stay on the same plane or they put you on a different one.
If you have a connection then it is a different segment.
