A NYSAC statement quoted by The Ring magazine reads, "Since the fight lasted more than three rounds after the referee's decision not to count the knockdown and the boxers adapted to the referee's decision, the decision was deemed to have no significant impact on the verdict of the fight."
It is possible that a rematch between Davis and Roach will take place in the near future. Roach is contractually entitled to it, although it's not clear if he'll use it.
