Also, redeyes into ATL often use the inner runways for landing simply because there are virtually no flights departing before 0730.
You overlook the simple mistake that could arise if the outer runway lights were not illuminated and the inner ones were, with the taxiway also illuminated. Simple assumption is that the one to the right is the inner runway, rather than the outer one, as the other runway even further out is not illuminated.
Happened at Gatwick a few times, with operaters who weren't total muppets.
