Two sparks for each coil firing like two gaps in the same wire. When there is an arc the firing voltage is really not very different through the side of the connector to ground than through the plug to ground. The act of arcing finishes the circuit although one of the gaps is now outside the cylinder.

Thanks for the explanation. It's a bit over my head, but I'll take your word for it.
