What Does "4 Life Sentences" Mean?

I demand a cite that all people have noses.

In any case, it seems to me that when dealing with a life sentence with the possibility of parole, multiple consecutive sentences make sense; it’s just another way of saying “life with no chance of parole for twice the normal minimum time.” If they’re concurrent sentences or sentences without the possibility of parole, it would seem to have no meaning save perhaps a symbolic meaning, such as three life sentences as punishment for a triple homicide.
