Well, we don't know for certain that Greninja is Ash's last quite yet. Just that Sceptile is Sawyer's. Considering Greninja hits the field after Sceptile is already out, we have no way of knowing until it airs (or the Pokenchi preview).
Follow-up question: if Ash switches out each Pokemon after they win and thus doesn't lose any, or simply never switches Pikachu back in after Aegislash, how would the win be over the top? It's a legitimate strategy and was the way Paul beat Barry 3-0 after all.
Well I like it when Ash wins battles that comes very close to him losing but he pulls it off anyway. If he wins 6-4 here then I rather see the winner of the next match win 6-5 as it would bring more tension for the final of the league.
