The clip finished before he leaned in aggressively to the referee forcing him to back away. So doesn't show the full story.
It's irrelevant anyway. The rule breached is clear, he touched the referee in an aggressive manner. Straight red and the range of punishments outlined earlier. 6 months is the suggested starting point. Hence me saying 10 games would be lenient. If the suggested starting point is applied he won't be playing again until end of September/beginning of October.
You can argue it all you like, but as it stands, those are the rules.
