Dana:
Although the wand thing is highly confusing in its rules but from 
what I understood of it, DD did not want Snape to be the rightful 
owner in the sense that he could use its power. The death was 
arranged and therefore Snape would technically not have defeated the 
owner of the wand. So Snape would, like LV, have owned the wand but 
not the powers contained within it. It would from then on just be a 
normal wand just like any other with no one ever again being able to 
defeat the owner for its powers because DD had been its last rightful 
owner and because he was dead, he could never be fought for it. 

That as I take it was DD's plan but Draco disarming DD made him its 
rightful owner.
