Here the problem with your theory.
That is a 2 channel coil (wasted spark system). It fires #1 + #4 and #2 + #3 at the same time as pairs. That means when the #1 cyl is being fired on its exhaust stroke, #4 is being fired on its compression stroke. (ignoring the other coil, for now.) Switching 1 + 4 does nothing, except move which terminal, on the same channel of the coil, the wire attaches to.
With this 2 coil system, wasted spark system, you always have both plugs firing on both the comp and exh stroke. One is being fired on the main coil (on purpose), the other is being fired on the secondary coil (as wasted spark).
