Yup. I had a similar experience couple of days back when FB listed three of my albums and correctly predicted the place names for confirmation. I was shocked when it _correctly_ predicted the location of one of my private albums which is an obscure town in southern India. Given that most of my pictures were taken with cameras with no geo identification mechanism, I can only conclude that they identify the location based on any comments and similar photos available in _my_ network.
