Thats the one million dollar question here. Whatever it could be 
could be the same reason why she was able to defy Voldemort three 
times before.

in order for Harry to have the protective bond of Lily's sacrifice, 
she had to die to protect him.   Now, naturally Lily didn't know this 
and certainly Voldemort didn't but JKR did.    Perhaps she wrote it 
like that simply to add the element of Lily's sacrifice and the 
affect of it on Harry as well as the long term affect it could have 
on the entire plot line.    IMO, that's why Lily had to die in the 
book.    As to why Voldemort stated it later on, perhaps he was just 
remarking that it wasn't necessary.     

Greatelderone:
I agree her sacfice is one of the keypoints of the book. However if 
Voldemort was just going to kill her after her son then I don't 
really see how it's a sacrifice.
