negative pressure in the pipe if both r connected to the same pipe and there is no vent in between . this is y they r usually connected individually to a trap with free flow and air vent giving it a break so as not to suck the water from other pipe systems .

If you flush and find water coming out of the base, it's a bad wax gasket. undo the water line and empty the bowl, turn it upside down and remove the old wax gasket. the new one only cost a couple of dollars. Simple task.
