Yes. Because the formula incorporates speed.
If you ride 20 kilometres in an hour, and you go out for a 1-hour ride, you've burned 400 cal in an hour.
If you ride 25 kilometres in an hour, and you go out for a 1-hour ride, you've burned 500 cal in an hour.
As for elevation ... usually, what goes up must come down. So you spend some time and energy getting up the hill, but then you coast down the other side and you don't expend much energy at all for the speed you're going.
