No, I think the method described above means you will be installing all
the packages from the repositories, i.e., over the network unless the
packages are on the original install CD/DVD.

I'm not sure how to do what you want but dumping the contents of
/var/cache/apt an restoring it to your new system may do the trick. I've
never tried it so I'm not 100% sure about this.
