because they weren't going for an accurate depiction because that would probably violate some NDA, so instead they put everything they know on there inaccurately, but still including the details that they knew of. Besides Matt admitted that he threw that together really quickly, hence the slanted part on the wrong side of the box, and the cd slot on the wrong side of the box.
Its really not all that hard to understand, I don't see why there is a debate about it.
Why would they have included the slanted part on thier "mock-up" if they didn't know there was going to be a docking station? That is extra work that you wouldn't do on purpose unless it had a purpose.
