Yea but who saying that Sasuke coudnt escape other way ? Because when Sasuke was caught in itachi genjutsu he destroy it without anything.
He said that he couldn't maintain Susano'o while he was affected by the sound Genjutsu

. Sense Saskue isn't a sensor, he couldn't
Edo tensei no. You need preparation for it.
I said without Edo, didn't i ^^?
He can dodge one but if here would be many Arrows ?
Unless Sasuke can maintain several full fledged Susano'o clones at once, i don't think there are more arrows.
