Why E?

In the video explanation, putting E in sunset violates the 4th rule where exactly two students review the same play or play(s) as each other. Can someone please explain this?

Is that for this question, or for a different one that may have added some other constraint? I think we could absolutely put O in sunset and still have the two reviewing the same be ok. For example we could have

J: T
K: T
L: U
M: U S
O: U, T, S
