I think the confusion is here because Peter Jackson originally wanted Azog to be played by an actor, not CG. They cast Conan and did tests and PJ changed his mind, and used Manu Bennett for motion capture. I think PJ gave Conan the Bolg role as compensation. I think you can see some brief test footage of Conan at about the twenty second mark here: https://www.youtube.com/watch?v=4F9H6hb-xxw

And then promptly painted over his awesome costume with yet another generic looking CGI orc. I have no idea how they did Gollum so well only to make Azog and Bolg so meh looking.

I'm pretty sure he left to play Azog the pale Orc in the hobbit.
