Yes, thats the point of disconnecting. If the swaybar is connected, it keeps the springs from stretching as far as they can resulting in one wheel coming off the ground. Disconnecting the sway bar allows the springs to stretch all the way out leaving the axle and all wheels touching the ground for better stability during offroading.
Here is an example. I have stock suspension on 31's. With out disconnecting the right front tire would not be touching the ground in the pic, allowing the jeep to rock back and forth, but since I am disconnected, all 4 tires are firmly on the ground.
