Tee Hee! I had seen this one, it's ...erm... inspiring
From watching the other Beyonslay moments of glory, it seems that the set-up between the two blockers is something they have practised a lot. It's working really well on most Jammers, it seems, even Suzy Hotrodhttp://www.youtube.com/watch?v=gMJrQvOscfQ
(although this was in 2007, I doubt she'd get hammered out now)
The thing I can't figure out with Slay is if she released Rocket on purpose come the outside line, to avoid an Out of Bound Block or if she's just lucky the poor Jammer fell off by herself!
She's still sent to the box, mind, but I can't really see why...
