At the end of the day they still made the right decision regarding that 40/20.
The video ref has been used to determine 40/20s, but the times I've seen it happen is to check where the ball actually went out.
Then why not use it for every close call. Raiders kicked it out on the full before, exactly the same line ball call and it wasn't looked at.
30-12
full time (well almost)
Gee Souths have a Wazn type backline.
