It's probably not so much a _security_ issue as it is a
_privacy_ issue. In the same way that it's no-one's business
what library books a person has checked out, it's also no-one's
business what products someone has purchased from an on-line
mall or how much he has spent there.
Keeping the two sets of information separate is safer for the
fulfillment house in case of some catastrophe like a systems
failure, a security breach, etc.
