I think the spec[0] has a revealing example for this:

* preceding-sibling::chapter[position()=1] selects the previous chapter
  sibling of the context node

So I think your XPath expression checks to see if there are any
preceding section siblings, not /any/ siblings.  I think you'd want
something like:

    not($node/preceding-sibling::*)

But that's untested.

Good luck!

Take care,
