Think of it this way:   a document is created based on a default
template that has definitions for a harmonious set of styles.  When
the document is saved, it saves the definitions for all of these
styles, not just the ones actually in use.  Imagine if it were
otherwise.  I create a document that uses only header-1 and default
paragraph styles.  If I save with only those definitions, what happens
when I (or someone else) tries to edit the document and wants to add a
header-2, or a list, or a quotation?  These style definitions would
not exist.

So, you really want to save the harmonious set of style definitions,
so these styles have expected relationships in terms of font face,
size, etc.

That said, there is nothing wrong, from an ODF perspective, to omit
unused style definitions.  You could create a document like this from
the Apache ODF Toolkit, and it would load correctly in OpenOffice.
But, depending on the intended use, the user might expect to be able
to pick from the full set of styles.

It works like this:  Automatic styles are the styles created on the
fly when the user directly applies attributes to objects rather than
using a predefined, named style.  So if you select some text and click
the bold icon, and increase the font size to 14pt,  then an automatic
style is created to express that combination of attributes.
