But Orci and Kurtzman did not change their minds about their own script, nor do they contradict their own facts in the comic prequel they conceived.
The explanation shown in Countdown is the same as in the film, but the film explains it much more briefly.
What is stated in the comic is stated in the film, if that helps. Orci wasn't lying in interviews, nor was he making up explanations to soothe the egos of ill-informed fans. He was talking about his own script in as much detail as he could without giving the whole story away months in advance.
