I believe Team taka had other plan and Sasuke just wanted to do his own stuff(being an badass).The reason i said this is because Jugo did not understand why Sasuke want to be hokage or his change or attitude.
I believe Team taka suppose to do a side mission while the edo kages do their part to stop the jubi or Madara becuase Karin,Suijestu and Orichimaru have not arrive yet in this chapter,there could be a possibility they collecting item or researching inorder to take down the jubi.I also believe Sasuke other reason to join the battle is to Make his sharingan or EMS get experience fighting enemy or observing Naruto and Sakura progression or stalling till other taka members arrive.
