That's cuz the entire episode has more cuts than Naruto vs Sasuke final vote2 fight.

Meaning the next episode has potential to be one of the greatest ever. Im guessing they'll change script a lot and make Momo much powerful, so that Naruto and Sasuke will be struggling hard with him. The preview already suggests it, because of Sasuke's actions. Sometimes when your most powerful attacks don't work, the simplest will. Either that, or Momo beat them so hard, they're both nearly out of chakra and literally using whatever they have left. You can see the desperation in Sasuke there and if im not mistaken, his sharingan is off as well.
