This appears to be just a naming convention issue. All the potential problems of staging environments can occur, for the same underlying reasons, in the approach advocated here, but they don't happen in staging merely because there isn't anything called that. Personally, I think the approach advocated here is feasible, and even necessary if you are operating at global scale, but I am skeptical of tendentious stories about how it makes a number of problems just disappear.
