It's just a lot of crap floating in my head...
Trying to type everything coherently is the big challenge.

Pete_89T2 said, the twin tower leading coil is just like a regular single tower coil except it has two towers...outputs...in parallel.
As long as the coil can discharge it's charge potential, it doesn't matter if it fires out one or both towers.
In an ideal situation, it fires two (identical?) sparks out the twin towers.
In reality, the wastespark system doesn't allow for balance loads across that twin tower leading coil.
One spark is firing in a pressurized, air + fuel combustion chamber - more resistance to firing a spark across the gap.
The other spark is firing in a highly charged, ionized (exhuast) gas, decreasing pressure combustion chamber which is a whole lot easier to fire a spark across the gap due to 1) less pressure and 2) ionized burnt particles of carbon.
It's this imbalance that causes the misfire of the twin tower coil.
