This seems to imply the owner's right to "access" their device ends at the moment of theft. I don't think it implies that. But the two rights are in conflict and need to be balanced. One does not automatically override the other in all circumstances. It would probably ok to access the phone to locate it, but spying on the thief like in the video seems to clearly cross the line of legality. Of course, this also depends on the jurisdiction...
