Because of the uncertainty principle there's always a probability that the electron will change it's state. so if we take a set of base states where each state x corresponds to the electron being at atom x then if atom x has a "hole" (missing an atom) there's always a non zero probability that an electron in the state x1 will go into state "x" and then the hole will have moved to the left. (the same thing applys to electrons at other atoms)
