Of course ..it is a Waste Spark DIS system. They are in series and one fires on Event stroke and one fires on Waste stroke. That is how you can run 6 cylinders on 3 coils...they fire two cylinders at once, but b/c one is firing on the Exhaust stroke, it is a WASTED SPARK and means nothing.
My concern now is do you have fire at the plug under the coil...
A test is to lift that coil ad use a plug wire in place of the Plug Connector [ what you call post/boot] and see if that has spark.

But don't disconnect the other in series plug.

..or, you can swap the coil with another and see if the misfire moves with the coil.

If you have no spark under the coil along with 5, then you have a bad trigger circuit in the HFM control module or a broken sensor magnet on the flywheel. There are 3 segments on the FW, one for each coil.

test that plug under the coil.
