It might be the case that she groups them by sales volume so they know what to focus on in each store. For example if Apple Regent Street sells mostly iPhones and iPads, then the marketing and layout will be tailored with these two products at the fore front, and moving the Macs etc to a secondary location.
Knowing these two popular products, they can then arrange accessories accordingly, have more staff that knows iPhone and iPad etc.
I certainly hope they don't try to take this to an extreme resulting in an inconsistent experience across Apple Store, which unfortunately is the case for me between Sydney and London. I'm wowed by the experience in Sydney but having been to Regent Street here 4 times to get something, not once have I walked out impressed at all.
