That's the cause of this entire debate. You seem to be defining "multi-Doctor" as "two different incarnations interact with one another" while others are defining "multi-Doctor" as "two different incarnations are in the same story." In fact, the term "multi-Doctor" can even be seen as including Last Night where multiple Doctors (albeit the same incarnation) interact with each other. At least with the specification of "multiple incarnations" we can eliminate that last one since they're both the Eleventh. According to the second interpretation, the situations of Four's flashback and One's appearance in Assimilation² and Listen respectively absolutely fit in many people's eyes.
