No matter how carefully orchestrated they are, sometimes, they are going to be doing more or less the same thing -- not necessarily in the same scene, where the question is who is the point of view character (and thus boosted in importance). But in rapid succession. Dealing with a bureaucracy, for instance.
There's a certain amount of inherent difficulty in varying scenes. Even when the character's reactions differ, there needs to be treatments of before, after, or at to keep things moving.
