Why did Voldemort die though he had Harry's blood?

I believe that Harry's blood could never protect LV the way it 
protected Harry. Lily's sacrifice didn't make Harry immortal, it just 
gave him protection from LV and LV alone, and not from any danger in 
the world. 

I think that's why DD told Snape it is essential that LV kills Harry 
himself. If someone else killed Harry, the soul-bit would have been 
destroyed, but Harry would have died (even though LV was still alive), 
because he is not protected from other people, only from LV. Harry can 
stay alive under two conditions: 1. His blood must remain in someone 
living (LV), and 2. He must be killed by LV himself.

Harry's blood in LV's veins has the same protection - it protects from 
LV, which makes no sense at all. How can it help LV survive? Maybe if 
Voldie suddenly started hating himself :-), and decided to commit 
suicide (hard to imagine)- the blood protection could have stopped him 
from hurting himself - I don't know, even this is doubtful. 

As it is, LV died, because, despite the fact that he shared blood with 
still living Harry, he didn't kill himself. I mean, maybe technically 
he did :-), but it was not his intention. It was more like an accident, 
he didn't direct that AK at himself. Or maybe Harry's blood never 
protected LV at all, maybe it can only protect Harry and no one else.

BTW, reading this thread, I had an impression that posters understand 
the situation differently. Some of them, including the original poster 
(sorry if I'm wrong :-), think that Harry's and LV's blood is the same 
blood (Harry's), and, judging by the answers, other posters believe 
that LV only has a drop of Harry's blood, and the rest of LV's blood is 
his own (pre-GH, I suppose). To be clear, this post is based on "the 
same blood" premise :-).
