“The expectations should be equal for actions with nonzero probability”—this means a CDT agent should have equal causal expectations for any action taken with nonzero probability, and EDT agents should similarly have equal evidential expectations. Actually, I should revise my statement to be more careful: in the case of epsilon-exploring agents, the condition is >epsilon rather than >0. In any case, my statement there isn’t about evidential and causal expectations being equal to each other, but rather about one of them being conversant across (sufficiently probable) actions.
“differing counterfactual and evidential expectations are smoothly more and more tenable as actions become less and less probable”—this means that the amount we can take from a CDT agent through a Dutch Book, for an action which is given a different casual expectation than evidential expectation, smoothly reduces as the probability of an action goes to zero. In that statement, I was assuming you hold the difference between evidential and causal expectations constant add you reduce the probability of the action. Otherwise it’s not necessarily true.
