I realize but upon closer inspection such difference could be explain by mutation. The whole point of this is that it is unlikely every legionaire from one or both of those legions what slaughtered. There were some survivors and they were incorporated into the remaining legions. They could have just been imprisoned though. I really hope they come out with another novel or something explianing what happened to the other two Primarchs. I am willing to bet one is still alive.
