By virtue of a win over Team WCW and Team Piper at Uncensored 1997, the nWo has the right to challenge for any WCW title at any time.
Strictly speaking, that means they could challenge for the World Title (containing the WCW World Title), the I-C Title (containing the WCW U.S. Title) and the Tag Team Title (containing the WCW Tag Team Title) in the WWF. But of those titles, only WCW's Big Gold Belt remains on TV.
So theoretically speaking, we could expect any of those men to get a shot at the World Heavyweight Title at any time, because they can challenge for any WCW title.
Not that Vince (nor anybody else but me and the guys at DDT Digest) would remember that, though.
Nope, because the UK mag probably isn't part of the WWE organization (yeah, that term should be used loosely these days...) Same reason why Scott Keith can have the scratchy WWF logo in the cover of his book.
