I agree with your interpretation. It would seem to have more to do with the slowing sales numbers for tablets as well as the incorrect assumption we would be in a post-PC era at this point. That day will come eventually and while large tablets may not be the answer, Apple is certainly hoping it will be. There has to be a good bit of concern at Apple that they are still largely dependent on the iPhone.
