That's because the battle was too quick Lol. Again, sasuke's PS tanks any black balls and limbo damage while cuts down madara with his rinne tech. The only reason madara escaped was because of limbo. Madara only has one limbo which sasuke can see btw so if he can wait till limbo separates from his body to take care of that, he takes out the real madara same way he did when he bisected him. Dual rinnegan jj madara would beat sasuke there's no denying that.
You forget that madara in jj mode can tank everything sasuke has, even only with one rinnegan, it doesn't matter whether he's cut in half or ripped apart.
Sasuke can see the limbo clone, but madara is very fast too, if sasuke teleports to him and pierce him he would heal the damage, or switches with his limbo clone and attacks directly with his staff.
Amateraus wont do any damage, madara would absorb it
Ps can be destroyed with black balls shots, maybe not with just 1, but madara has more of them and they causes big destructions.
BTW madara has also rinbo hengoku, which owned all bijus at once, PS will be broken after a hit.
Don't forget sasukes technique has a cool down.
Madara can fly, should he be cut in half his upper body just can fly out of the limited range sasukes jutsu has and heal completely.
Madara don't need 2 eyes to preform wood style, so wood dragons of madara will absorb sasukes PS or damage it at least.
His sharp raiton jutsus also can cut sasukes susanno
and what about wood style bun shins of madara ? why wouldn't he use them to make it more difficult to hit the real body ?
If madara wouldn't have his great regeneration feats, sasuke would beat 1 eyed rinnegan madara, but he has and sasuke will be outlast.
