In case of ELOL can be ELŐL, or ELÖL, both have different meanings. ELŐL (with long umlaut) means 'from in front of sg/sy' while ELÖL (with short umlaut) means quite the same as ELŐTT. MÖGÖTT and HÁTUL also have the same meaning in the daily life. (I am not a language teacher but a native Hungarian who cares about his language.)
