I would not use the $pos variable, but instead,
        <xsl:copy-of select="preceding-sibling::row[string()][1]" />

The [string()] predicate makes sure we select only preceding row nodes
whose string value is not ''.  [1] lets us select the first one, in
reverse-document order from the current node.
I haven't tested this, and I'm afraid of pitfalls related to current
node list and the binding precedence of [], but it seems like it should work.
