The splitter is a bit short, but it should still help to produce some downforce. Look at it this way: As you drive faster, the air pressure at the front of the car becomes greater. The splitter catches that high pressure air and pushes the front of the car down (downforce). The longer the splitter, the better the leverage.
In terms of aerodynamics, it should also help because the farther the front of the car is pushed down, the less air can travel underneath it.
