Self-destruction of "essentially divided" Dark Lord

Hi together,

I've continued pondering over the prophecy...

I think the word "either" is the key to the real meaning, for it can 
have two diametrically opposed meanings:
1) one OR the other
2) one AND the other

Second ingredient:
The scene in chapter 22, where Dumbledore consults one of his 
instrumens. It shows him a puff of smoke shaped like a snake. Then DD 
says, "Naturally. But in essence divided?" and the snake divides into 
two snakes. DD observes this with "grim satisfaction."
There hasn't been any solution for this scene, so I think it contains 
an important clue.

So here's my latest proposal:
The Dark Lord is in essence divided, because he is composed of two 
personalities: Tom Riddle and Lord Voldemord. Harry Potter has the 
power to vanquish the Dark Lord by making Tom Riddle and Voldemort 
fight against each other. Riddle and Voldemort will kill each other 
and both die.

Do you think that might work?
