Sasuke is the summoner and can summon Manda as close to him for eye contact as he needs.

Not only that, Itachi probably needs to get pretty close at this point for Tsukuyomi, since his eyesight is so bad. Can't make eye contact if you can't see the eye. It actually lines up with Sasuke vs Itachi because Itachi got in Sasuke's face to use Tsukuyomi
