This is easily visualized if you take it to the extremes. Imaging blocking your intake prior to the throttle body with a plate with a 1/2" hole in it. Imagining you could even support the engine with such a hole, you would need to open your throttle very far to reach the same airflow you would have had without the plate at a smaller throttle opening, however once you open the throttle to achieve the same flow, everything is the same. It works the same in reverse with less restrictions instead of more.

Your example doesn't make sense. If you have a restrictior plate with a 1/2" hole before your throttle no extra amount of throttle opening is going to make more air flow through that 1/2" hole. That hole is the limit. Your throttle at idle probably has less air flow than that 1/2" hole but once you reach the flow limit of the hole that's it.
