Their are two coil towers per coil.  There are in series on the 
wasted spark system.  Any yes, the polarity is reversed for each
pair of plugs.  I think it was Buick that used a platinum tiped plug
with platinum on both the center electrode and the ground just
because of the reversed polarity.  They wanted 100000 mile
plug changes, so....
