Even if he was patrolling because of Kage summit or whatever, it still wouldn't mean that he was doing this for Root and any similar organization.
The way he worded purpose of his travels, it won't surprise me if Oro team Taka these days spend their days on rehabilitation of their own victims or their families or the war victims in general and Sasuke goes to check upon them. Or he maybe just touring the world. There can be many other scenarios- Anything but playing a second Danzou. That's kind of defeats the purpose for those two( Naruto and Sasuke) anyway.
I don't believe Sasuke would spend close to ten years touring the world making up for his sins.
in 699 that he told Sakura he would travel the world in order to redeem himself,but he did mention he would be back.
In 699.5 which takes place two years after 699 Sasuke has still not returned but is seen in the movie's trailer protecting Konoha.
In 700 which takes place six or 7 years into the future we see that Sasuke did come back and settle down with Sakura. I believe Naruto and Sasuke are both protecting Konoha, Naruto as the,public face " Hokage" and Sasuke from the shadows as either the head of a newly refurbished reformed root/ head of Anbu.
I do not believe Kishi would have Sasuke roaming the world aimlessly for close to ten years abandoning his responsibilities to his home, family and friends.
By settling down with Sakura he made a decision to come back to Konoha, he chose to be with his family and home.
