Shouldn't a diverter valve only have three ports, an "in" and two switchable "outs?"   The left hand 4th valve appears to add in a length of tubing like a normal valve, as long as a conventional 4th valve, or maybe the elusive quint valve.  It is also possible that my eyes are deceiving me;  it's a little hard to track all of the tubes in the pictures.
