This picture may tell the bigger story.
While looking at it I noticed 2 more holes that are currently doing nothing.
Could they be for the front mount for this bar?

Looking at the diagram there are a few bushings that would off set the bar from the mount a little bit. I also found a perforated, but not removed hole in the back of the side panel. I think in front of that bracket.
I'll look tonight at the front 2 holes to see if they are also threaded and if the panel has perforations there as well.
little b it looks like those tabs face in for some reason. It's probably just a bad drawing. I wonder if the rear leg of the bar extends down beyond the wheel arch and rests on the horizontal frame member near the side of the seat? That way the frame member would take the weight and the bracket sorta just holds it in place. The DAS bars sorta do this, but they mount using the rear seat hinge point.
