I thought it was odd they didn’t apply the lines during the game, not on my feed anyway. But wouldn’t argue that aspect.
The last player to touch the ball was an opposition player, I’m not sure what the technicalites are anymore they’ve fiddled with it that much - Ive spoken to professional coaches in the game, who can’t rhyme and reason it and struggle to apply the rule to coaching given the variance in application.
To my mind if the last touch is of the opposing team your onside, it’s how I was coached, I’m sure there is a technicality in the rule for interruption, but thats part of the problem in application and variance around it.
