What I meant was , When you used first genjutsu I lost control on where I was , and what was happening , to encounter it I would use Kai , but if you use 2 Genjutsu's in a row , Since the first jutsu allows you to make it Double Layered so when you used 2nd jutsu If made another layer over the previous Genjutsu.
When I would kai out of the first genjutsu I would see you infront and attack you thinking I am out of Genjutsu , While I'll be trapped in 2nd Jutsu without Knowing and the person infront of me is another illusion as well. Which will give you chance to strike since as I would strike it would vanish into petals giving you an Perfect Opening.
