Then how can you say that Rodolfo is pulling Judo throws out of his Bjj training if he's actually training Judo separately to learn those throws?
In part, because he trained under Julio Cesar Pereira, an Oswaldo Fadda black belt AND judo black belt himself-that particular lineage has preserved the gyoku waza taught by Maeda to Gracie and Franca-it's a non-Gracie line of BJJ, and preserved the pre-war throws and foot and leg locks that Gracie jiujutsu often lacks, or frowns upon.
So it's because throws like morote seoi nage have been part of BJJ from the beginning, and because of the way he modified it for BJJ competition: going to both knees immediately, throwing uke at an angle instead of directly in front, and placing his body at an angle-all of these negated (somewhat) the disadvantage of exposing the back in that particular type of competition...
