That pseudo-win-phone interface was my first thought too, a really bad idea IMHO, as you pointed out it will only confuse users.
Something I also thought was that the idea is to create a better opinion of the windows phone, and to confuse users to buy windows phones in the future. I also wonder how nice this pseudo-win-phone will play with all the other android apps.
(Disclaimer: I have used a WP7.8 phone and hated it, since then I developed a hate for the windows phone, I feel so limited when compared to android)
