I don't know for sure, but I'd guess those upward kicks are likely there to reduce rear lift, or to compensate for a less than optimal backlight angle (too steep, as is my guess on the Opel). The addition of a spoiler as we know changes the "effective" rear angle.

Rear lift isn't an issue for me because I don't drive anywhere near fast enough for it to be a problem.
