Interesting find... I'll show some spark plugs!
Actually, I am very intrigued and amazed at my findings. I always thought that the leading coil would be tapped in the center and that both plugs would fire Positive. I changed out my spark plugs last night and came to an amazing find. The Leading coil is NOT center tapped so one leading plug fires Negative and the other fires Positive. See the attached picture!

In the above picture, you can see that the ground electrode on one spark plug is barely worn but the positive side is burned to a crisp, The other spark plug is exactly opposite.
This means you could, in theory, swap your leading plug wires between plug changes and extend the life of your spark plugs.

Smells like 2 stroke.

... honestly I actually have noticed a difference in the front and rear leading plug wear but I never read anything into it...

Think TIG welding. Electrode is negative because when it comes to electron flow, more heat/damage happens to the material they flow to, in a much greater degree, than the material they flow from. When TIG welding aluminum, you turn the welder on reverse polarity (electrode positive) to ball the end of the electrode. This is for AC welding of aluminum.

The coil will fire weakly and yes it stresses the coil.
