Another theory is that they were gotten rid of in a way Lorgar wasn't there to see.
Magnus talks to Mortarion about how the last time 9 brothers gathered together was for the (supposed) extermination of one of their brother Legions. Mortarion tells Magnus to be quiet because they were supposed to never speak of it again.
Perhaps this all happened before Lorgar was found? Or after he was found, but for one reason or another, Lorgar wasn't able to make it to the destruction of the 2nd/11th's Legion and Primarch.
To be fair, though, I haven't listened to Butcher's Nail. I'm getting on it now.
