Cam position sensing w/o a cam sensor

IIRC, it is a two tooth wheel (180 degree oppossed teeth) on a cam with a
sensor mounted in the valve cover.  It is very similar to the crank sensor
setup except for it's location difference the the difference in the number
of teeth.  I don't see why they used two teeth 180 degrees opposed because
you then lose the ability to sync your signal according to a particular
valve event (say combustion vs intake on #1).
