That's correct, these are instructions for switching from vanilla or if
you want to *very* safely recompile everything making sure you get
hardened.  It is the most conservative path but also very time consuming.

If you're starting from scratch, just grab the latest stage3 *hardened*
tarball, start building your system from there and save yourself the
time.  You will gain nothing but recompiling the tool chain and
system/world.
