That would the same case for any other wing mounted above a spinning wheel, as they create a region of low pressure above the wheel which would help accelerate air under the wing and aid in production of downforce. The CDG wing was never tested because it was only envisioned for an ideal straightline case where one car would be perfectly in line behind another car on a straight. What would happen in any other scenario wasnt really though about from what I understand. either way, the teams quickly put down the CDG idea and it was left behind.
