Great People, Random Kill?

By Esperology, in Sid Meier's Civilization: The Board Game

I will be getting the expansion soon, so I was reading through the rules and found something I would like some clarification on.

Keep that in mind as I have not seen any of the cards, so any rules specified on them are unknown to me.

On page 12, at the bottom, it has an example of killing a great person.
There are two great artists, one in play (faceup) and one in hand (facedown).
One token dies a horrible death at the hands of an assassin.
One must be randomly selected to be discarded with the token.

Now, since the rules seem to indicate that the applicable great people that are faceup are to be included in the random kill, do they return to play faceup after the death or has this process removed them to your hand (facedown)?

Or, is this a moot point as all great people that will be in play faceup have the stipulation that they are always in play faceup?
