Not all debian packages are reversioned. Actually only 1000-2000 are I
think. We only need to touch the Debian source package if we have to
make changes so the vast majority of the packages are synced straight
from Debian unstable by the Ubuntu archive administrators. We try to
keep the number of ubuntuX versioned packages to a minimum as each
release we have to examine those packages that have since changed in
Debian and resync/merge the Ubuntu changes back in. It more-or-less
happens the way you are saying. We have an automated system called
Merge-o-Matic (MoM) that automates some of it.

Hope that helps.
