I can see a great many people downloading it and then getting confused for a split second every day between the two and keeping track of what they were using each for. Over time that additional mental fatigue translates into lowered satisfaction with the device. It's similar to the fatigue of maintaining different versions/copies of anything in parallel - code, email inboxes, a story that you've told people about an event.

It's much simpler and less fatiguing to have one copy of any given thing. While I might chafe at their deciding this for me, I think their policy makes a certain amount of sense in the context of keeping (most of) their users loving their devices.
