If the magazine and the survey are both addressed to the same housemate, then which one of the following could be true?

When given the two scenarios instructor deduces she cannot but both M and S with Jeanie since it violates some rules which is understandable. however she did not visit another scenario which give Jeanie M and S and G (forgot his name) L while P goes to R (forgot his name) which leaves F to give either with G or R. Can i get an explanation how this scenario does not work?
