"There seems to be a sharp drop-off line running north/south just west of Mongolia & east of Novosibirsk." That line is too sharp for a 'Hey, that's China!' stop. Besides, it's unlikely that many of them could locate China correctly, due to the generic lack of geological, geographical and topographic studies in US schools. I think they got an America (as in: continent) centred map, something like this [1], with the small difference of being cut somewhere at the eastern parts of India, instead of the eastern borders of Iran.
