^ameno is to fast, correctly used it would allow sasuke to be basically directly in front of narutos with with full powered chidori (which is also already swung and enters his skul in the very next moment), that should easily pierce narutos skull and kill him, or a strike with chidori sword in the same manner, there are a few ways to use ameno for winning but its due to plot (meaning CIS) and/or context (meaning: he had reasons like "didnt want to kill him for real" or "was to exhausted in order to think of this method" or "didnt have enough chakra for that" etc) that he didnt do it...
