This statement is wrong.
As a matter of fact, I dont think it could possibly be more wrong.
It has to do with traction. A tire can only provide X amount of traction at any given point, lets use for example 100% (the most traction the tire could possibly give, as when it is sitting at a stop)
Now, you have to devide that traction between three forces, Acceleration, Handling and Deceleration. On a RWD car, entering a corner at high speed and applying throttle you are using that tire for two things. Following the front tires, and propelling the car. Run out of traction, and suddnely you are a drifter. The use of a downforce wing in this situation is to keep your rear end planted and following the front of the car.
A FWD car does not work in this way. Enter a corner at high speed uses the rear tires in one way, to follow the front. Where as the front tires are being used in two ways. Too much throttle will break the tires grip and the car will 'nose' or slide in the direction of its momentum. (not around the corner.

)
Sorry for the long post. But i wasnt gonna say that you were wrong without a good explanation.
