Macbook Air and two thunderbolt display. Not working

I just found a curious video that I always have been wondering about since i have a 11" MBA. Its two Thunderbolt displays connected to a Macbook Air 2012. Its not working :/



There is altho another way to get two displays. Its called DualHead2Go and is a converter that you put between your mac and 2 displays. Its not really two displays but its two connected displays that is recognized by mac as one big display. So if you put fullscreen on movies it will be in the middle. Not on one. The menu will also be in the middle spanning across both displays.
