If my understanding is correct, that means people travelling between European countries will not be able to access the eShop and other things that require NNID's unless they register a new NNID for every country they visit.
The policy seems to begin June 13th. - EDIT: Note: Policy doesn't seem to start June 13th.
Sorry if old.

Update: Possible mistake.
To use Nintendo Network you must register a Nintendo Network ID. You must provide accurate and complete data during the registration and update your registration data if they change.
The Nintendo Network ID is linked to your country of residence that you indicated during the registration. If you move to another country, you may not be able to use your Nintendo Network ID (including Digital Products) and you may have to create another Nintendo Network ID if you want to enjoy Nintendo Network in this new country. If you move back to the country, in which your Nintendo Network ID was registered, you will be able to use your original Nintendo Network ID again.

I think this has always been a part of their User Agreement, Australia still has the 2013 version for example, and it also includes this same text.
