Disconfirmed also doesn't mean what people use deconfirmed for. If anything anti-confirmed (not a word) or disaffirmed is closest
Also 343i is known to have lied in the past, and it's possible that Frank was left out of the loop or his knowledge was, or has become, outdated. Further, he's not the creator, just a higher-up in the company that manages the Halo franchise. He wouldn't even have the final word on Chief, and to keep things under wraps he might even be bypassed.
