No idea. The point is: the guy in question has a passport full with stamps. Only the "cancel visa stamp" is missing. So, he can mail it to his friend, that is the guy who asked the question. And the author of this post can go with the passport and the agent to immigration.
No idea what you are nitpicking about. I guess passports never get stolen. A damn bag that happens to have a passport inside gets stolen.
