No - that's fine. But remember that your ticket must have the coupons to get you back to your country of origin and that these will count towards the 20 segment maximum on the ticket.</font>
I'm just the guy in the peanut gallery with no inside information, but I always thought that an rtw "required" you to return to starting point (broadly defined, e.g. country of departure or in the case of U.S., U.S. or Canada.) Failure to do so may leave you open to having the segments you flew repriced as point to point.
Not that I've ever heard of anyone being caught.
