Fair, I should have been more precise about the placement of the “must”: Inside the if-then rule, not in the outer game description. The card frame and the bar frame differ in how the rule is expressed (not just here, also in the Wikipedia article), which I guess strongly influences how people parse it into a logical relationship in their mind.
(Besides: The bar scenario also comes with a prior understanding of how to parse the rule, since everyone is familiar with it and its exact meaning, while the card scenario does not and therefore has more room for a parsing failure.)
Er, maybe she edited in later, but this was in GradientDissenter’s wording too, no?
