I think one started a fight he couldnt finish and the other chose a direction and took his whole legion with him.

One probably tried to take power from the emperor and Russ was sent to put him down.

The second chose to take his legion with him beyond the borders of the known universe for reasons such as. He didnt like what happened to the first one and wanten no part in the Emperors plans or maybe he was gifted like magnus and saw something that needed dealing with outside the known universe.

Hence 'the purged and the forgotten'
