On out-of-sample points, i.e., fresh points generated according to the same (uniform) distribution. You can generate as many of these points as you want to get better accuracy. If you want an exact answer, calculate the area where $f({\bf x})\ne g({\bf x})$ and divide by the total area (which is 4).
