It's basically inception, that's how I think of it
I think it has a similar effect as the sword Itachi's Susanoo had. But I'm not really sure myself.
Itachi ordered himself to 'protect Konoha' though KA, this was in conflict with Kabuto's will, which Itachi was bound to through Edo Tensei. Apparently, KA overwrites that and Itachi was no longer under Kabuto's will.
It was supposed to be used on Sasuke, so he would protect Konoha instead of trying to destroy it.

I actually don't really understand how koto-amatsukami is working? could someone explain it to me??
