Its either or not both.I would say no. This is because the Chakra is not connected to him any longer. It has already formed the mist, and has no connection to him.
Either he or his chakra has to touch you. Shadows aren't connected to him yet they can use ftg. on him and vice versa.
Not what I'm asking.I've never seen that done an I'm not sure a seal can be put on the air..
Everytime Minato did FTG there was a seal on a object to go to..
