The BK's are fat because of the pump. RD pumps don't handle pressure very well from what I've read and a taller reaction chamber would just cut down on the efficiency of the unit. Being fatter compensates.
I think there is a little more to it than that. Here is a link to the BK home page from Germany where they are built if you want more information. http://english.royal-exclusiv.de/index2.htm
