Yeah - like the video said, any sort of hatchback with a roof spoiler is essentially acting like a rear wing, or a rear spoiler since that's the end of the car on shorter vehicles, and hatchbacks; that also is apparent, but I was referring to deflecting the airflow over the back of the car as explained in the video.
