He is really pushing himself

 

[FleeOnSight]

He's trying as hard as he can to keep up with the rest of team 7.

 

[Styles]

He overused his Rinnegan to much strain.

I thought it was leftover from Amaterasu and that's why she noticed

 

[Unorthodox]

it was for reading amaterasu incase she trys to do her ice trick

 

[riley freeman]

Wasnt he trying to prepare it for when she tries to switch dimensions? i could be wrong

 

[Trashboat]

I think she was preparing for when Kaguya switches dimensions, like she noted that if she goes to the Ice dimension, Sasuke will just use Amaterasu.
