He needs a 2 hour 100 nm dual x/c flight in day vfr conditions, and one of the same in night vfr conditions (SEL rating, I assume).
Some of this might have been accomplished as part of the private and instrument requirements (vfr conditions); otherwise it appears the school is correct. Also, I'm not 100% sure about the instrument x/c counting - there may be an interpretation otherwise, even though the flying may have been performed CAVU.
