The standing variation of this pass is legit and this pass is still taught in Torrance. I saw an old video of Helio showing the standing this to Royler and the details he uses lock the hip and make it very difficult to maintain the triangle. Chet Schemahorn Gracie Jiu Jitsu Black Belt taught me how to pull the standing variation of this off. Pedro Sauer also teaches this move. I am not saying nobody can hit the triangle off Helio's variation, but it isn't easy.
