He needs to touch obito with his hand to start yanking out his soul and we don't even know that he knew how to do that without obito teaching him. Obito just needs to touch nagato on a part of his body that's not his hands and obito presumably has full intel on rinnegan abilities. Nagato doesn't have any good counters to obito's intangibility except maybe the deva path but obito might know about the time between deva path attacks if BZ told him about it.
