I don’t think rule utilitarianism, as generally understood, is the same as expected consequences. Perhaps in practice, their guidance generally coincides, but the former is fundamentally about social coordination to produce the best consequences and the latter is not. Hypothetically, you can imagine a situation in which someone is nearly certain that breaking one of these rules, just this once, would improve the world. Rule consequentialism says they should not break the rule, and expected consequences says they should.
