I've noticed this pattern with other high IQ, well-written people. It's almost a defense mechanism, retreating back to the medium through which they're usually most successful. "If I can put things eloquently enough, perhaps they'll understand why I did what I did."

It's not dissimilar to some of the ripped athletic types I'm friends with that try and use their size to an advantage even when the situation definitely doesn't call for it. If a tongue-lashing or an ass-kicking is the immediate gut response, it's probably not the most pragmatic, I've found.
