Use a straight edge on your monitor in line with the head tube and you will see the the axle is well in front of the steering axis.

I know, I perfectly get that, it's obvious that having a straight fork but with an angle at the joint with the head tube will have the same effect. What I was saying is that in the previous posted picture, just that picture, the increased rake of that very specific bicycle was likely consequence on the curvature, so I am not sure how we did get here to be honest.
