I think it allows the upper 3 elements on the outer side of the wing to flex downwards on high speeds and it comes up again on low speed. Per default the outer part is set up a bit higher (adjustable by the 2 screws i suppose) to support low speed front downforce. Nice stuff!

I think you are on the right trace:
The aluminum flat bar does not look flexible at all. If I wanted something not to flex this is what I would use. On its step there may be a joint as the lower part is wider. So this thing is just a support.
On the other hand there is no visible connection at the slot with the yellow circles. So I think the upper, green connected part flexes in two steps and the round "hooks" on the side control the flex.
This would also include the front wing adjustment: The screw just controls the prestressing of the two, round "hooks".
