So it's better to have two green pixels, so that the higher value of green required doesn't require boosting the green 'one ISO value' up. This is also the reason that when testing very high ISO performance, the blue channel is usually the one with the most noise. That's because most 'available darkness' shots are taking at colour temperatures well below 5000?, so to get reasonable white balance the blue channel has to be seriously amplified, meaning it has little dynamic range left and a lot of noise compared with the red channel, or the green channel which starts out with twice the 'power'.
