Didn't hear it either. I was at the game and I refuse to watch that abortion of a match ever again. So unless someone posts it here, I'll probably never know.
Yeah, it's a bit of a grey area, this one. I think that the fact that Burgess was within the 10 when the ball came off Shillington in the first place, sort of negates that. The rule now is that if you are off side (i.e. in front of the kicker), but more than 10 metres away from the ball contact, you are then back on side. I think that if you are inside that 10 metres, it doesn't really matter what happens as you are deemed to be invovled in the original play.
It used to be different but I'm sure the rule has changed within the last 5 years.
