You're absolutely right Ingar!
I did a huge amount of experimentation today and found out the real story.
When you say \end{olddescription} in the ending part of the modified version
of description, the \end{olddescription} constructs the macroname
\endolddescription and runs whatever is stored in that macro. Without saving
\enddescription to \endolddescription, the call to \end{description} will end
any environments started in the beginning section of the modified copy of
\description, but it will not perform any explicit writes declared in the
original end section of \description.
I'll be covering this in a new LaTeX quickstart for LyX people.
Thanks,
