The article says that the two diagonal elements in the table of those four combinations, U = RI (or dPhi/dt = R dQ/dt, the classical resistor) and Phi = RQ (the purported memristor) describe the same fundamental element, the resistor. Which is sort of obvious, as one is just the time derivative of the other. [Edit: got the direction of which is the derivative of the other wrong on the first try]
