Yes, because the computer has much more precise control over the throttle position than your foot can provide. It is constantly watching the speed and the variation as well as rate of variation, and a well designed system will always only give as much throttle as needed to maintain your set speed. People are always wobbling their shit and keeping a sort of constant state of acceleration which requires more fuel than just maintaining speed.
