Our cars don't even have brake ducts do they???

The driver side opening in the fender is for the intake. If they made that opening larger so that there is an opportunity to channel some air into the wheel well, maybe I can see what they are saying, but that would also require cutting a hole in the fender liner and so on.
The passanger side opening is for the transmission oil cooler, which already vents into the wheel well.
Then, there is the question of what blowing some air into the wheel well accomplishes exactly in the absence of ducting to a modified back plate. I am sure it does something, but I don't know how significant that can be.
