I think the point can be made more simply as follows:
Consequentialism is a theory about which states of the world (and thus implicitly actions) are preferable. For it to be true does not require or imply that worlds in which some particular bounded agent (or even all humans) believe in consequentialism or attempt to act according to it’s dictates is preferable to the alternatives.
The obvious and simple counterexample is to have an alien race who tortures all humanity if they use their mind reading technology on anyone and ascertain they believe in consequentialism. In such a situation consequentialism obviously entails that it is better for everyone to believe in some non-consequentialist view of morality.
