Their initial design goal was 3(+) speeds, but the method they chose allowed for 4 speeds just as easy as 3. Essentially, each shifting mechanism they incorporated doubled the potential ratios. One mechanism would be two speeds, two mechanisms allows for four potential speeds. If they added a third, it would be 8 speeds. Rather than try to explain it in greater detail myself, I'll simply use the wonderful resource they posted on the gearbox (with nice pictures that explain it better than any amount of paragraphs ever could).
