On the Indian/Afghan swords I have handled with this feature it has always struck me that the sweat spot of the blade was just an inch or two below the visible spine projection, so I think your theory could be possible Tim.
Another possibility that occors to me is maybe you only want a sword to penetrate to that depth ? any more is a waste of both sword blade & your energy?
Perhaps its also like the cross bar on a boar spear? in a more minimal fashion? you dont want a determined but run through man coming at you up the blade beyond that point?
Just a few thoughts that popped up.
