Perhaps they selected AH first before they knew they were on an island, and stuck to it after they found out because it's not worth switching techs around once you've started. Or maybe they did switch techs around, and that's also why they haven't finished a tech yet.
I'd be very surprised if there was no land based food in any of the starts. The demographics prove they're not identical. I think the fact that we have fish rather than clams or crabs, and two of them, and one coastal even, matches the fact that we have no land-based food resource ourselves. I expect the capital BFC food and the island total food will be about equal, but other teams won't have nearly as many fish as we do.
