I think you can say something similar about the original problem. P(decline oracle’s request) can (for the new problem) also be phrased as P(oracle is wrong). And P(oracle is wrong) is zero in both problems; there’s no evidence in either the original problem or the new problem concerning the case where the oracle is wrong.
Of course, the usual Newcomb arguments apply about why you shouldn’t consider the case where the oracle is wrong, but they don’t distinguish the problems.
