I think they want to highlight the custom silicon models that they have so far because we are now at the point that probably every product will have its own processor so you need some kind brand of what the goals are of Apple's strategy in the future. Also, its really good marketing and allows everyone to have the same talking points because if you want to explain the naming scheme of any processor manufacturer it will take longer than the amount of time that anyone has an actually attention span for people not interested in the subject already.
