The idea is that it's already awkward to have two opposing wards in the same location, and that in those cases only one should remain anyway. Control over the bush should pass over to whomever is controlling the center part of the lane and took the opportunity to lay down their ward and/or destroy their opponent's. Even at its most ridiculous, i.e. with both sides fighting each other while simultaneously to win with the last ward standing, warding would generate tension and zones of conflict across the map, and thereby force even the most passive lanes to occasionally fight for control. By contrast, the current state of warding often renders laning stale and occasionally too slow, as wards early on are extremely potent at deterring ganks and are hard, if not often impossible to remove.
