I have no idea and I cannot speak for Roleta but maybe its becuse he wants Bruno to put his full attentions into building Roleta UK and teaching his students?. other than that i do not know.
I tried this over sutton once ended up hurting my neck need to give it another go I think
When using the pass I would prefer my elbows to be in tighter. Triangle and Omoplata seem obvious from that angle. I also like to grip the collar palm-up and elbow down to stop him turtling, I prefer the position over attempting to go straight to the choke. Just an opinion.
Fernando is competing in Brazil in March (not sure when he's back in the UK). Bruno will also compete in the UK. Before coming out to the UK he won gold at the Rio state and silver in the Rio Open International (both at black belt). After 10 months on focusing on developing beginners he needs to get match fit again. Thus we are now doing more hard sparring with a personal focus outside of training beginners etc.
I was being facetious.
