I interpreted that to apply to uniques with the same unit name, so that you can't wish for any one in particular. After all, you can't wish for 'Megera' or 'Tisiphone', if memory serves -- you have to wish for an Erinyes, because that's the unit type. Same goes for Gorilon the Heliophagus versus Mastema the Heliophagus versus Makabiel the Heliophagus et al. On the other hand, you could wish for the King of Deeper Earth specifically because that's his unit type.
