No, it's still Haise, but he's accepted that Kaneki does exist and that both of them want the same thing but are scared what will happen to them afterwards.
And "I lied" ment that he didn't want Arima to find out what he ACTUALLY did and who Hinami was to him in the past so he lied to him about what really happened.
what did the "i lied" reffered to? anyway, that little kid is cute....
wait,, IS HE KANEKI?
