Nobody's saying that Superboy is 100% controlled by genomorphs at all times, only that there might be lingering traces of control that will allow the Light to take control of Superboy at a later date. He's a sleeper agent. Bear in mind that the Light only mentioned they had someone on the inside, not that this person was actively working for them or feeding them information yet.
