Doesn't really look like they actually touched the camber, they did however adjust the toe-in. You're toe was a little out of spec prior, which would cause the tires to drag and wear quicker than they should. Afterwards, you have a slight toe-out condition, which tends to aid turning or makes the vehicle more agreeable to turns. Adjusting the toe will sometimes cause a very slight difference in camber/caster, due to the angle of the tires with the wheel centered.......they basically gave you a toe alignment, but the camber was well within spec to begin with.
What you didn't provide is the caster numbers before and after, while which do not usually cause tire wear, can result in a drift or pull condition. Your camber is set that you'll have a slight drift to the right, not much by a very slight amount. Hopefully the tech left more caster on the right side than the left to more than compensate and setup a slight left drift for road crown. (Usually they'll give the passenger side more caster to allow it to creep up the crown just a bit).
