From my understanding of it one of the angel rolls pops up higher than the other. You can basically angel roll one where just the bottom tip passes accross the shoulders, allowing plenty of space for the other to pass 'normally'. Josh can sometimes get it with our juggling staffs. I'd really love to learn it with our contact ones, but it appears to work only with relativly short staffs. Really long ones will always crash :-(
