I remember seeing this on a ticket years ago. There were two boxes, one indicating that a radar gun was used, the other saying that the person was visibly speeding.

As OS X becomes more popular it's pretty much inevitable that people will *want* AV on their computers. Be it from the paranoid to the clueless who "heard from a friend of a friend that Macs are insecure" -- or just someone playing it safe -- a move like this would make sense to ease consumer fears. Yes, they already sell AV products from third-parties, but in the same way Windows has its own set of security tools this is Apple's way of showing that you don't just have to trust them, they're actively involved in proving the safety of their product.
