You may notice that ImmobileChaosBot (the Annie tester in the Vel'koz ingame leak) has been around and is probably working with Riot; When the new Healthbars were released to the PBE, Riot Nomegeta explained and demonstrated stuff about it through pictures, that feature ImmobileChaosBot- http://2.bp.blogspot.com/-kjPpA1sg2nY/UnLmel6MV0I/AAAAAAAAIrs/tx_6Gs2qmYo/s1600/healthbar.png (THERE IS NO NOME is Riot Nomegeta). My point is that you're probably right because you can see testers (ImmobileChaosBot) that have shown that they worked (and might be still working) with Riot.

P.S: ImmobileChaosBot has an NA account named like so. And he is, yet, not listed as a Red/Rioter on the forums.
