It's not clear to me why this was added, can you explain?

I added the comment in the code. Done.

     if (!authenticated_username_.empty()) {
       token_service->LoadTokensFromDB();
     }
+#endif
   }
   if (!user.empty() && !IsAllowedUsername(user)) {
     // User is signed in, but the username is invalid - the administrator must
     // have changed the policy since the last signin, so sign out the user.
     SignOut();
   }
 }
