Recall Willey taking a catch as a sub a few seasons back and was awarded 10 points (and the subsequent price drop). Don't see how Cooper is any different in this cirumstance.
Can never access the rules for point scoring on my phone , my understanding is that substitute fielders are not awarded points.
At the time of the catch , Cooper was a substitute fielder.
Once he was X-Factored in he can then be allocated points for any actions.
Maybe I understand the definition of substitute and X-Factor differently to others.
