I think the rationale is always going to boil down to: "nobody carries ONLY an Amex card anyway" so they may as well try and claw back the % difference in rates, without thinking that a customer would ever have a payment method in mind BEFORE the decision-making purchase. In theory, that could very well be true depending on the type of goods, similar to what ChrisCh was saying - impulse buys would definitely benefit from the strategy. Pre-mediated buys like cars, shopping-list groceries not so much.
