Mafia 106. Cradle of Dragons

I see a contradiction. Remember the example with the dragons sending units to each other.
In this case, Aeon acted first, sending everyone (including Bjorn) to Bjorn. Thus, Bjorn was sending everyone back to himself. If this is an illegal move, Bjorn fails. If it's legal, it's a success, but the essence remains the same - regardless of whether Vasya was initially sent to Bjorn or Aeon, he should have ended up with Bjorn, and not where Bjorn sent him (i.e., to Aeon).
Where is the flaw in my logic?
