<xsl:template match="link//llnode" mode="yyy">

that matches anly llnode that is a descendent of a link node.
so this
<xsl:for-each select="*">
selects all children of those llink nodes.

Your other template is almost completely different.

<xsl:template match="link" mode="yyy">

that matches any link node

<xsl:for-each select="//llnode">

this selects all llnode from anywhere in the document irrespective of
which link node was matched.
 the " ..some action.. " is now executed on the link node not on its
children as in the first template.

You could yuse .//llnode in the second template to find all llnodes
below the current link, but in either case if you know a more specific
path than // it would be good to use it. // is very expensive it causes
a search the full depth of the tree looking for the specified nodes.
