Nope, it's garbage i'm afraid.
If you move to another country in the same region (ie Sony Europe is the whole of Europe, Middle East Africa and Oceania) then you can do it but you still need to create another user on the PlayStation for the new country and link the accounts on the PS4. I think that's how normal game sharing works.
If you move to the US or Canada for example then you are sh*t outta luck, they actually recommend that you buy a new console lol and setup a new account.
