The NEC requires that metal conduit or armored cable be bonded to ground at both ends in order to (quickly) pass fault current. In a situation where you have a ground conductor within metal conduit/armor that is grounded at only one end, that conduit/armor becomes a choke to fault current that will impede its flow.
