She did not assess the situation. At all. She was still falling down and was panicking like hell. She was also stupid enough not to realize that the ice dimension would help, even if it was for just a second.
Is that a Viz scan?
She was indeed pankicking but like I said before, Kaguya said "So both of them were Ashura's reincarnate" which means she actually thought
Sasuke was really Sasuke. That means she was aware of
Sasuke's presence which implies that she didn't realise it was Naruto.
And yes, they are VIZ scans.
You should have made a "plot hole" option. There are several others in the fight.
This plot hole can easily be solved if Naruto did actually transform into Sasuke perfectly.
