Except for the fact Obito teleported the specific body part Sasuke was targeting, thus showing he seen where Sasuke was aiming. Therefore, he could clearly see Sasuke. It doesn't matter how far away Sasuke was. Obito wasn't like "I'm just going to guess what part of my body to make go intangible and hope he doesn't hit anything else." No. He watched Sasuke get close, seen where his blade was headed towards, and used Kamui. That means he seen his every move. So even if Sasuke was going different directions, he'd still see it like he was able to see the direction of the blade which was slashing.

It can be argued of him keeping up with KCM Naruto. Naruto was talking and clearly not serious.
