The ball was played on the 30m. He was offside when the ball was played but continued going back to the 20m then started going forward. Thus he is onside.
That's a good point, but I don't know the correct ruling on this. I'd still believe him to be offside regardless of whether he runs back to the 20m line.
We see players offside in games ignore attacking players when they could so easily run back to the full 10 and then make the tackle.
