the manga ended dude and sasuke admited he lost... [to save his own life...coz at last he understood that his further madness could kick his own ass hard by zeus naruto ]
He lost the aesthetic part of the battle, he lost the battle of wills... But physically they tied Inb4 the incoming "Naruto could have kept going" spambots: no he couldn't, he would have bled out and died with Sasuke if he even tried to.
Point is, they BOTH were unable to do much moving
they BOTH would have bled out and died if the fight continued
they BOTH lost an arm
they BOTH had .1% chakra left (0% chakra =death)
