A-1 is the producer studio. Satelight was the animating studio. Satelight owns their animation. Bridge cannot use Satelight animation because it is a Bridge-drawn anime. Two different studios animating, two different ownerships. Since A-1 has nothing to do with the animation, they cannot just insert Satelight animation into Bridge work.
