When one of the ends is pushed upwards (suspension compressed), the SB transmits part of that force to the opposite wheel. Effectively, with a swaybar, you have semi-independent front suspension as the sway bar connects both A arms together. Thus the A arm on one side can't compress without the other slightly compressing as well. The same is true for extension (droop). This inhibits flex for the axle that it is placed upon. End of argument.

However, you don't only have one axle flexing. Both axles work together to articulate over bumps. Dues to the configuration of our trucks, front IFS and rear solid axle, they don't flex very well. The rear flexes hugely, while the front just doesn't. Thus the body motion is almost entirely determined by the front wheels. The rear sway bar opposes the rear flexing, and actually forces the front to flex a little. I drove around a little without a rear swaybar, and overall suspension flexed less and the body had more lean and the handling was weird. With no front swaybar however, the rear is more able to force the front to flex, thus the truck's suspension is more balanced and the truck flexes better.
