No, these are not options. The two steps are meant to be run in-order.
Ports can (and a few exotic ones will) install files in other locations
in the filesystem that are not covered by the rm -rf in the second step.
If you do not uninstall the ports (or at least deactivate them), these
files would be left on your disk, and the next installation of one of
these ports would fail with the same problem you've been seeing.
