he probably just decided not to make it that obvious so soon, to have a little bit to wonder about between 2 and 3. just like Padme's family didn't make the final cut for 2 but they're supposed to make it into 3. It's obvious from that info who Lucas has decided ordered the clones. He's just changing when he tells everyone. Its in the shooting script as well as the novel so it might have been a last minute decision.
