I don't think I've seen this posted before. After you leave the room the Shadow Clone shadow stops following you so there is no visual of the skill after this happens. If you try to undo it you will freeze in the casting animation (client side only I assume). If you press attack or shield you break the casting animation and can then recast the skill to get the shadow following you again.
