I really don't think this ruling has as much effect on Threat from the East as it does on reviewing how several other cards work. This is an example of a player being forced to deconstruct card text as if they were Vulcan in order to play the game correctly. It is clear that not everything is obvious on some of these cards.
See the Stay of Execution plot. That text is even worse because it's not literal. Kings and Queens are still actually killed before being returned to their hands.
