Question: Regarding that move Hawks does where he lifts his fingers and adjusts then in a different position in order to get the advantage and win, a) what is the significance of doing this (what exactly is he doing) and b) is this even legal in a real arm wrestling tournament?
Answer: It's a regrip to get leverage. Yes it's legal. The best arm wrestler in the world Devon Larratt does it with perfection. Usually works only in a strap match.
