Yeah. He was already extending his fingers but then his brain lost control of the movement and the fingers just struck Sasuke's forehead. I don't know what he was saying, but I wouldn't be surprised if it was something along the lines that this was his second favorite ending and that Sasuke should get close to Madara instead to defeat him in time. Maybe he even told Sasuke to take his eyes for the eternal sharingan. Itachi already knew he had lost at that point. I mean, anybody with eyes could see the man was nothing but a walking corpse anymore. I don't know why Sasuke seemed to be panicking. All he would have needed to do was to take a step back for every step Itachi took forward, for those steps were indeed numbered already for ol' Itachi.

I also don't know why anybody would say Itachi won the fight. The last man standing wins a fight, not the first man to drop.
