I think you are right, that was not an accurate statement. I stand corrected, the larger gap can cause more electrode wear.
While there is a benefit of a larger spark plug gap wear isn't one of them. As long as the coil has enough power for a specific gap it won't really change anything but at larger gaps where the stock coil wouldn't work and the hotter coil can then it would wear the electrode more due to it having to cross a larger electrical potential.
Running the larger gap does have advantages to fuel economy, efficiency, emissions, etc if the coil can support it.
