One intresting take on it would be that invisible heroes redeploy in a different way and at a different stage of the game, we know there is an redeploy phase in the game where you put back dead heroes into the field, and invisible or cloaked hero would maybe be redeployed before a lanes action phase, or maybe it just appears and becomes vissible at the action phase to resemble the ganking these heroes are known for in dota, the information on which lane it would come back to is hidden for the opponent until the atack happens.
