I have come upon on a better nonsense , on their part judging by this top upper panel Garra,Naruto and Sakura are approaching to Sasukes location and Sakura will see Sasuke and all of her focus will shift on him
.

I hardly doubt that is the case because whatever Gaara is doing is solely because of Kurama's plan. So I doubt that Sasuke has anything to do with whatever Kurama wanted him to do
Madara killed saskue away from everyone else, plus the Mokutens are in the way so no one can really see him but Karin can sense him. I think Dr. Snakes and his posy of friends will rush to save him. Making Sakura focus on Naruto.
Kurama may have been planning on this from the start, the other half of the nine tails has more chakra than the good half, so Kurama may have let go so Minato could give Naruto more chakra.
