This ratio allows for a relatively simple 2x2 repeating pattern. That makes interpolating the values immensely simpler.
Also you don't want the red and blue to be too far apart, reconstructing the colour signal is difficult enough as it is. Moire effects are only going to get worse if you use an even sparser resolution.
