More that it requires active and time dependent history to know the state of the device, making it not fundamental in the sense that the resistance doesn't depend on history. It's a fair point I'd say, and they're clear that this isn't something that diminishes utility of any practical device. Just that it isn't fundamental. This seems clear if you define fundamental things as not requiring history or energy to be defined. If you don't define it that way I'm sure you can come to a different conclusion.
