He's still swinging and missing a fair amount but he's laying off bad pitches that he was swinging at early in the season. From what I've seen, he's still struggling with the fastball inside but he's no longer flailing at pitches all over the place (up, down, inside, outside). It's possible the book on Buxton read "don't throw him strikes, he'll swing anyway". That book will need to be revised soon if he keeps it up. I've always believed this will be a baby step process. Byron needs to make several adjustments and it appears he has begun to make at least one of the necessary changes to his approach.
