That's an excellent summarize . Now here are my 2 cents , as we see Sakura is out of chakra just like Naruto was when he fought to save her life from Garra but Naruto manage to pull the Kyuubi's chakra so he can save her , so i think as she realizes that she's gonna lose him at the same time realizes how much she loves him Sakura gonna release the full power of her Yin seal to save him to maintain him in life just long enough till they reach to Minato since i think that's were they are going to.
If they go to Minato, oh my God, more incoming comments from Minato to Sakura. Oh crap! Obito can parallel her now!
