remember the ballast output to the coil is allways hot, no matter the ign switch stage
That's where you're wrong, in Start the blue wire (IGN 1) shuts off and the brown wire (IGN 2) powers the ignition by bypassing the ballast, in Run the brown wire shuts off and the system is again powered by the blue wire.
At no time are both the IGN1 and IGN2 circuits powered at the same time.
