Kind of, it doesn't use a skirt or suck the car towards the ground. It uses a fan to guide the air allowing for steeper diffuser angles than would normally work. So you get an indirect downforce improvement.
In the end you get an effect that is 1 or 2 orders of magnitude smaller than sucking the car to the ground with a skirt.
