Well, to answer your questions :
#1: The reason that the Human Genome reference with not completely match
anyone's personal genome is that everyone has slight differences in their
genome compared to everyone else.. that is why I do not look like you, I
am better at math while you are better at english, why you are susceptible
to different types of cancers than I am, etc.
#2: The point of the human genome project is to get a reference copy of
the human genome. The project is assuming that everyone on this earth's
DNA blueprint is about 99.99% homologous to everyone else. Once the
blueprint is made, then scientists from around the world can then search
for those finite differences between individuals. You are right that it is
statistically mistaken, but in order to take a sample of a million peoples
genome's with today's technology, it would take a much more concentrated
effort by the entire human race. We are taking baby steps here, not steps
of giants.
I hope this helps,
