Well if he died he wouldn't go to Ogygia, he would go down to the Underworld and with Thanatos back in action, I don't see him getting out if he died. The only people seen so far that can come and go freely are the gods because they are all powerful and immortal, so I think the clause about never being able to find the island twice would also apply to dead mortals. As we have seen, just because you are dead doesn't mean you can't die (so in a way, even the dead are mortal).
