Considering how obsessed with image, marketing, etc, Apple is, I would be extremely surprised if the Marketing department weren't hugely competent in this matter, including knowing about user-agent strings, logs, etc. Ask yourself: would Steve Jobs have known about this? Yes, of course. So, why wouldn't the person he hired? This is not a clueless marketing department we're talking about, here... it's probably the most competent marketing departments of any technology company in the world.
