What is the difference between the last and the second last point?

AFAIU, Phillip is concerned about the development process of ELPA core
packages.  While developing such a package, one wants to edit the
git-controlled files directly and probably also load these files instead
of the (git-uncontrolled) ones in the proper Emacs core location, where
they would reside at least in a tarball release.
