Muneo SASAKI pays attention to the fact that the Japanese word indicating the full delegation of state affairs (authority to act as the Emperor's deputy), to which Mototsune was entitled during the Era of Emperor Koko, was not explicitly used in these two shochokus, and asserts that Mototsune felt antipathy toward the Emperor because he suspected the Emperor might be trying to reduce his political authority, rather than because the term "Ako" had been used, leading Mototsune to request that he be given the same level of authority as he had held during the era of Emperor Koko.
そこで佐々木宗雄は、基経の本心は「阿衡」という言葉よりも光孝天皇の時に基経に与えられていた政務の全面委任（王権代行の権限）の授与を示す言葉が2度の詔には明記されなかったために、天皇が自己の政治権限の削除を図っているとの反感を抱いて、光孝天皇の時と同等の権限を求めたのではないかという説を立てている。
