I may be misunderstanding the question, but i'm going to go ahead answer what I think you might be asking.
So the OS is about John's way of thinking. It's not about everyone's way of thinking (look at the Sixth Sense storyform, same situation, the OS is all about "what's wrong with Cole?"). What that means in regards to Dramatica is that Hansen won't (necessarily) have conflict because of Hansen's way of thinking but that he, Alicia, the professor, the doctor, Charles, Parcher, Sol, et al will all have conflict because of how John specifically is thinking.
From a far off view of the story, the OS Concern across all four throughlines might be about how everyone conceives of John, or getting John to conceive of reality or something. Because John is schizophrenic and hard to get along with, everyone conceives of him a certain way and this brings about conflict for everyone. Conflict like subtle insults being lobbed where Hansen "mistakes" John for a waiter and John replying that Hansen's papers have no originality. Things like the professor having to tell John that he can't move forward based on his current level of work. Things like John's schizophrenia kicking in. Things like Alicia getting frustrated at how her husband seems distant causing her to have a meltdown in the bathroom.
From a zoomed in level of SP1, we still have stuff like Hansen, I guess, conceiving of John as the waiter. But I think you could say that John not knowing how to speak to the girl in the bar is a form of conceiving creating conflict for him and the girl. There are other small examples, I think, where the way John conceives or fails to conceive creates conflict for him AND for others.
But then you also have the big obvious example of John's failure to conceive of an original idea. This failure to conceive creates some tension between John and the professor when the professor has to tell him he can't advance. You could ask how that's conflict for the professor, what does he care that John isn't advancing? But the important part isn't that the characters care about it, the important part is that they experience the conflict. And in that scene, the very small amount of tension between them, i'd argue, fulfills that conflict for the professor.
The reason that "John is schizophrenic" is the OS and "John wants recognition" is the MC is because "John is schizophrenic" is something that, in one way or another, creates conflict for all characters involved where "John wants recognition" only creates conflict for John.
