My parking area slopes to the curb side so the curb side tires end up in the air. On a level area, If I start the auto level with the RV already lifted somewhat then all 4 tires can be in the air when it is level. If I start the leveling process with all jacks retracted and the front a little low then the tires end up on the ground. If it concerns you, I suggest you start this way.
If you completely suspend the suspension, the axles can drop to the point such that the shackles in the center equalized can flip down and it is a real pain to get them back to their up position. It just happened to me when I lifted the whole RV up to replace all of the tires.
