What you stated is correct and I received the same reply from Airbus. Interesting thing is the question about the significance of 3Tons was asked by one of Airbus industry instructor himself and the answer given by them was that engineering cannot not find any significance about it so they plan to delete it. But they have not deleted even now after 7years. When I asked them this question they gave me detailed reply as yours. Then I asked them to remove the earlier one from FAQ. They replied that the respective department has been instructed. But they have not done it.
