This just confirms that the turn is overbanked (the angle is greater than 90°), not that it is an inversion. Granted, there is a lot of debate regarding the definition of inversion, but generally, it is when the track angle is greater than 135°. That is the point where the track is more above the car than to the side.
I've attached a crude drawing to show the angles that I am talking about. The last picture (bottom right) shows the track at 135°, which is right at the borderline of non-inversion and inversion. Any greater angle than this and it is definitely an inversion, imo. In the picture posted, the angle more resembles the 115° picture, which would be a stretch to call an inversion.
