After that little incident three years ago at the Valley of the End, Naruto had the time to reflect in what he did wrong when he stood in Sasuke's path, so that he would never do the same mistake twice.

When Naruto finally spotted Sasuke and knew that he was in Sasuke's path, he put a KB instead of him. Apparently, Naruto got tired of getting stabbed by chidoris all the time.

Naruto, i applaud you.:nod
