I think these observations presuppose that at any given moment a
language or sub-language
has a well-defined finite set of words in it.  I am not sure I would
agree with this, even if you consider
an individual idiolect, given the productivity of certain morphological
rules (eg writing re-writing re-rewriting ... and so on), and other word
formation processes.

More generally this relates to the various observations about Zipfian
distributions in the lexicon made by e.g. Baayen, Gazdar and so on.
