In certain designs, metal 2 is used for power rails instead of metal 1, why ?

I have noticed that power rails are put on metal 2. Metal 1 is not used for signal routing or power routing. Why ?

Is it because at lower technology nodes, there is a lot of signal routing within the std cells so an entire layer (M1) is used up ?
