no, they didn't. Teamwork assumes that Naruto managed to win against Sasuke at the Valley of the End. It's mentioned quickly in a few places in the main fic, and a little more detailed in "Progression", which is a series of ficlets about Naruto between the Valley of the End and the start of Teamwork. Sasuke never managed to leave Konoha, Orochimaru was killed a few months later, and Sakura never had any reason to push aside her lack of confidence and seek out Tsunade. She has an internship at the hospital and Shizune, Tsunade's assistant, gave her and a half-dozen of other people lessons for a few months, but before Teamwork started, Sakura had never really talked with Tsunade one-on-one.

I am eventually going to mention what exactly went differently in the fight between Naruto and Sasuke, but since that's spoiler, i'm not going to say what. :D But yeah, I know exactly when and how it diverged.
