@Riot, Mordekaiser ultimate for spectators

This is a pretty simple question and hopefully a rioter sees this, anyways, when I'm watching a game with a Mordekaiser through spectator (such as pro play) how will his ultimate appear to us? The player gets his own little screen when he ults along with the target, will we see ghosts? or a 2nd smaller screen? I feel it would be boring just to not see what happens.
