Sephiroth acts as the new Jenova in AC. He has control over Jenova's cells. Kadaj is wrong when he thinks Jenova chose Sephiroth over him. Since Kadaj didn't exist back when Jenova was actually alive, Jenova had no way of choosing Sephiroth over something it didn't know would come into existance.
Kadaj freaks out like that because he sees all that is left of "Mother". All there is is a bunch of green goo that used to be Jenova's head. His reaction was perfectly understandable.
