I saw it as a way to humiliate the Shinigami and to use it to defeat the owner of the Bankai with their own Bankai. As all the Stern Ritter were told to fight the Captain that they stole the Bankai from, to further humiliate them. Also to make it less troublesome for the Stern Ritters, so that they wouldn't have to use their Vollständig.
