My assumption is that when their father had the Fenris twins restored he had Andreas' mind altered to erase the progress made in his Swordsman period. Either they wiped those memories out entirely....or, if they wanted him to retain the increased fighting skills he developed as Swordsman, then they just brain washed him to keep his old personality intact.
