This just popped into my head, and I got excited and wanted to share.
  We know that potions and spells are delicate processes, and messing
up a teensy thing can have dire consequences.  Messing up a teensy
thing can also have varied types of consequences (immediate, delayed,
smokey, stinky...).  If some of Voldemort is in (or somehow connected
to) Harry's blood, then some of Voldemort was used as "blood of an
enemy".  Since Voldemort is not technically his own enemy (unless you
wanna get super philosophical), might this be problematic for the
spell?  Or, could the spell somehow create a magical karma wherein
Voldemort is now magically bound to be his own enemy/ his own downfall?
