"Horus became possessed on Davin IV"

What? As far as i remember he wasn't totally on Chaos side until Istvaan III. After Istvaan he more and more descended into insanity reaching the climax at earth.

There is a slight difference to possession however. He is pretty much possessed in the final battle against the emperor, yeah, but even then it seems to be no 'usual' possession.
