Then, the same issue is for Garsha but Vanfeny has more chances to "survive" than Garsha. Even it is almost the same as luck, then I can say that Vanfeny has more chances to break through it because his block is higher than Garsha's luck

Espio didn't stated that Vanfeny needs to go back and help. He meant that if the opponent has the ball while on their DF line, Vanfeny has more chances to steal the ball and then goes for the goal to score because then, there are no defenders in his way to stop him on time.
