I'm not sure what you think that proves. A US URL works for the US and talks about the US? Surprising? Other countries are doing recalls too, and have pages talking about it.

Here is the Taiwan URL:

http://www.samsung.com/tw/news/product/galaxy-note7-announce...

Here is the Canadian URL:

http://www.samsung.com/ca/note7exchange/

Here is the Australian URL:

http://www.samsung.com/au/galaxynote7-notice/

Here is the Chinese homepage (see the pop-out note about the Note 7 to the left):

http://www.samsung.com/cn/home/

It is a global recall. You just cannot guess the URL in the way you think you should be able to.
