The beer comes in the form of 2ltr plastic containers with a valve on each end. Packed in the cap is a small connector tube with a pipe on the other end. Once inserted in the Sub the beer is chilled to 2c and as you pour it pressure is applied to ensure all the beer comes out of the container during use.
In that instance it was the first glass out of a new container so you do get a bit more head than you'd expect, if you pour it carefully normally at 45 degrees etc... you can get it better. However in Europe the norm is to have a big head on the beer like that - bit of a fiddle if you ask me to make you buy more in a bar lol!
