You are correct. Well, there's not supposed to be any preload on them. The bar end "flats" and the vertical link should be at 90 degrees to one another with the car in a resting, static condition. This allows you to tighten them to specification and during any body roll, the bushings will exert the same force (by storing energy due to deformation of the urethane) on the bar end regardless of the direction of deflection of the anti-roll bar with respect to the vertical links.
In picture "B" (picture "A" did not load, so I can't comment), the bar end "flat" is at an angle to the vertical link, thereby making it difficult to get the bolt tightened properly. Don't know what car it's on, but let's assume that the bar ends point to the rear of the car. In an hard right hand turn, the "joint" where the bushings and the anti-roll bar connect will get tighter and maybe tight enough to actually lift the wheel off the ground, while the "joint" on the left side will actually become looser, much looser than desired and not load the bushings on the left side at all. It would be like not having the anti-roll bar hooked up on the left side, or maybe having it connected but not properly tightened.
If, in picture "B", the links were too short, and we had the same hard right turn, the opposite reactions would take place at each bar end. The right "joint" would loosen, while the left side would tighten too much or reach the "limit" of the bushing's "squashiness" (yeah, that's a technical term) too early. It may be so tight as to make the left wheel break traction way before you wanted it to. Another undesirable condition.
Remember, contrary to what many people say, body roll is not evil. Some is needed to absorb the weight transfer over time (slow down) instead of immediately. Sudden weight transfer can overwhelm the tires and cause loss of traction.
While not the end of the world, picture "B" is a poor way to do it. If it were my car, and I had proper clearance, I'd go for shorter vertical links to get the relationship between the bar ends and the links closer to the 90 degrees, or bend the end of the bar ends to make them work (yeah, right), or find the right anti-roll bar for that car. My guess is that it's the right bar but the suspension height has been changed (lowered) with no consideration for the bar end/vertical link relationship. Buy shorter links if you have the clearance to do so. That's the only practical solution.
And they're not swaybars. They are anti-roll bars.
