In the top shot you will see he is running diagonally, not exactly straight back at his own line.
His hand closest to his try line touches the ball first and then the ball hits his other hand closest to his opponents try line
Therefore, at the first point of contact, the ball was propelled forward.
(From his back hand then onto his other hand closest to his opponents try line, which is in a forward direction)
It doesn't matter that it ended up going backwards towards his own try line.
These are the types of technical points that even got OJ Simpson off lol.
You obviously have no idea of the rules and have now introduced the useless piece of information that he was running diagonally.
According to your theory, where the ball ended up has no influence, as the fact he hit it forward from 1 hand to the other constitutes a nock on.
If your argument was correct, that the action of going from one hand to the other hand constituted the nock on, then why are players allowed to bobble the ball when they score a try?
Simple it didn't hit the ground or an opposition player in front of them.
From where he originally touched it and where the ball touched the ground (in this case the action that constitutes a nock on or not) the ball was further back towards his own goal line.
Play on every day of the week.
Just as well you weren't OJ's lawyer he would have got the death penalty.
