I think ECFMG doesnt really care that much. They would see AUA, a listed ECFMG school, cover for the KMCIC students and need not look deeper. I would think the concern would be come licensure time. It would be up to individual state or provincial licensing authorities how they would look at this. If you and I are confused about this AUA/KMCIC mix, I wonder what would happen when one of them start probing?
