I do see a "lip", which as has been discussed here elsewhere, helps the rear turbulent air behind the vehicle air reattach better to the rear airflow off the trunk lid.
I am not trying to open a semantics discussion, but believe clarity is important here.
On a historical note, I saw my first real spoiler on the winning 250 TR Ferrari at the 1962 Sebring 12 hrs. It was not intuitive as to its purpose or method at the time.

I believe that the Ferrari incorporated Richtie Ginther's spoiler,which he co-opted from his experience around flaps,slats,and spoilers in the US Air Force.If you have an side image of the Ferrari,look at the slant from the roof to the spoiler tip.As long as some of the downwash strikes the spoiler,you're on your way to eliminating rear lift.
