Could you be more specific about this references?

the Inkscape manual correctly says:
«The style (color, fill pattern, etc.) of the clones can be changed independently but only if the style of the cloned object is Unset.»
<http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Clones.html>
«The fill type can be one of the following choices: (…)
- Unset (necessary for giving different attributes to cloned copies of an object).»
<http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Attributes-Fill-Stroke.html>

In my understanding, individual clones can only change their style if the original object (aka the cloned object) not the clone (aka cloned copy) itself has its styles 'unset'. AFAIK this hasn't changed in recent Inkscape versions.
