I understand only half of what you are writing.
But perhaps this will help you: a more "path-like" clone can be obtained
by drawing a straight horizontal line, applying Pattern along path LPE,
then as pattern path *link* it to your master path (select master path,
ctrl+c, select 'path-like-clone' and click 'link to path'. You then a
somewhat of a clone. But you can set the fill and stroke regardless of
the masterpath's fill and stroke (unlike a normal clone).

Johan,

I believe the veIntersect element would do what he wants to achieve. Basically, it's a more useful type of clipping in some circumstances. If the image they showed wanted a better demo, they would have used a stroke on the larger object, because the inner "hole" that gets created would be stroked too.
I will email you off-list with a screenshot.
Cheers,
