Decreasing the flow path area will *always* increase the flow rate through the decreased path (assuming a constant pump pressure). In some situations this is known as the "venturi effect". The key to Grunff's assertion is that, when the heater is blocked off the flow through the *radiator* will be increased (not the total flow which would be somewhat less), but since the radiator is a far superior heat exchanger the total heat dispersed will be greater.
