That strategy seems to work pretty well, not so much because of SAing him but because it saves your energy for when he's in Hypermode. It seems that it's true that he won't teleport in Hypermode, but how long he stays in Hypermode varies; usually I can only get in two or three fully charged shots before he warps away. By that time I'm already corrupted, so I kill a Commando for the extra energy and the second time the Commander goes hyper I can finish him off.
EDIT: Heh, wow, this strategy works VERY well. I've gotten somewhere around 10 successful fights using this strategy in the last hour or so. :D (there were failures, too, but the success rate using this is much higher)
EDIT 2: By the way, it seems I'm wrong about him being unable to teleport when in hyper, but his being in hyper does give you a lot more time to shoot him; more than enough to get in two or three fully charged hyper shots.
