From my research, it seems that the ignition coil packs fire two plugs at once. For example the number 1 and 6 cylinders share a coil pack; the no. 1 cylinder fires at 6 degrees BTDC compression, while the no. 6 cylinder is at the same spot in the exhaust stroke. Would both plugs actually spark at the same time?
It's called a "Wasted Spark Ignition System".
Here's a link or two:
