Sorry, but we do not save or print to PDF.  We export to PDF.  Please be
aware of the distinction (and that we can use other OS provided print to
PDF).

The feature you refer to is known as a Hybrid PDF.  It started as an
OpenOffice extension but was integrated into LibreOffice core early in the
project. It is not enabled  by default during export to PDF, but can be set
as a persistent option for PDF export.

It simply extends the PDF container to attach the ODF archive of the
document.  Only LibreOffice is intended to extract the document from its ODF
container during import of  the PDF.  Apache OpenOffice may or may not open
recent LibreOffice HybridPDF.   Once embedded, the ODF archive is *not*
hidden inside the PDF archive, and other other programs may see it as an
attachement and could extract it.

A search of BZ with for strings "Hybrid PDF" should provide some context. 

As to security believe either  the ODF archive or the exported PDF can be
encrypted/password protected during save of the ODF and on export as a
Hybrid PDF.

As you note it is still a users responsibility to redact any content from
the document.
