One of my favourite moments, the forehead poke, is the anti's target. Like, seriously? How can anyone even say that? You can argue that he's doing it to distance him and Sakura, because Itachi did the same, but you are wrong, and let me explain.

Sasuke does it to show his affection for his family, if you couldn't even tell that from the picture because he is smiling. If he wanted to distance him from her, why would he have a genuine smile on his face?

The forehead poke is a symbol of love — please don't say that Itachi didn't love Sasuke — that runs in the family. Sasuke honours his brother, Itachi, by doing it.

He also does it to Sarada, his daughter, and it surely isn't to keep her away from him. See? It's all quite simple.
