Overlapped coils mean that someone have tapped the pins or/and also that the piano have been restringed with too much coils. I don't tune much "spinets" as we don't have often those kind of piana here, (while we have enough bad instrumnets to be pleased) I just don't recall having seen overlapping coil often, indeed tapping the pins is not a real repair and have some disavantages, like this angle question.
