There can be benefit to the design that is on there now. If the sides come down where the lower-hanging suspension and the wheels/tires are, then the lip is helping reduce the amount of air flowing over those components. The middle area under the car is usually higher than the suspension, so there may be no benefit in having the lip go down as far as the outsides... in fact, you may end up blocking more air than necessary, thereby increasing the drag.
Notice I say "can be" and "may" ... this is theoretical and would require some testing on your car model to confirm.
