Actually, look at the image again and think this through. By stiffening the front bar, you will lift the left front corner of the car to some degree. Where is that weight going to be transferred?

To the right front? only slightly, or not at all.. If you could hold the car in the state it was and screw around with the suspension at that moment, you would find the following:

Stiffening the front bar will lift the suspension on the left front. This will rotate the car diagonally across a line drawn between the right front and the left rear. It will have very little effect on the right front or left rear wheel loads. It will increase the load on the right rear.

So, stiffening the bar in this case will transfer some weight off the left front to the right rear. Now, because no weight (or very little) has been added to the right front, and some is being taken from the left front, and more weight is moved to the right rear, you could expect the car to tighten up, or gain a little push. That's why the general rule is, to tighten the car, stiffen the front bar, to loosen the car, stiffen the rear.
