I phrased that final bit very confusingly.

I just meant that a file which is intended to be installed as an
ELPA package might actually be loaded directly from some non-ELPA
source, or even evaluated via `eval-buffer', and so an approach
which depended on a *-pkg.el being present in the same directory
could fail in those situations, causing inconsistent behaviour.
