Mafia 106. Cradle of Dragons

Aeon sent it to Bjorn, this action is already completed. Then Bjorn sends it back, and Aeon has already moved.

Once again, for the slow-witted:
why doesn't the transfer from Aeon affect Bjorn?

And am I correct in understanding that if, as a result of any combination of transfers, the player ends up on their own space, they fail?
