I don't see that this contradicts my statements, which was that if you fired 6 .50 BMG at the same spot on aircraft for long enough you could cut it in half! In fact it explains how it works ( And why a different system should be used to increase your chances of getting a kill at other ranges), even though the circumstances to do this in real life would have been extremely rare.
As far as I can tell in IL2 we use the "point bore sighting" (I think the exception is in the P47 where you can alter one of the pairs of guns by changing the cannon convergence) where the guns are converged on a single point. (I use this for range finding in my skip bombing attacks- fire the odd burst until your rounds converge to a spot and then let the bomb go! It works a treat!)

The practice of converging all guns at some one point along the path of flight, commonly referred to as "point bore sighting", although producing heavy concentrations of fire at certain ranges, produces excessive dispersion at other ranges. Furthermore, heavy concentrations of fire at the selected ranges were found to be undesirable in that bullet densities far in excess of the required lethal density were produced, resulting in inefficient employment of the fire-power available.

Cheers and thanks for the link it was an interesting read.
