Orochimaru doesn't need to drown. He just needs to be unconscious which staying underwater for too long will do without air. Reverse summoning won't work cause Kisame isn't going to allow him to do that. Kisame has the speed advantage in the water. So him summoning wouldn't work since Kisame will already be attacking him. Even Gyuki needed to escape with ink. Orochimaru doesn't stand a chance in a water based fight against Kisame merged with Samehada.
