What happens is, when the "points" (sic) open, the magnetic field built 
up in the coil collapses, and the voltage out starts to rise... if 
there's no plug, ir rises to 20,000+ volts. If there's spark plug, the 
voltage increases to the point of arcover, then the energy dissipates in 
the spark in the gap and doesn't go above a few thousand volts.

If there's two plugs in parallel on the same coil... Random or not so 
random variations means that one of them will arcover first, then the 
voltage will drop as the arc eats the energy... and the other plug will 
not fire.
