You're not understanding what xsl:value-of does, I think.

In the XSL I quoted above, you have identified in your select="" a
node-set consisting of *two* 'name' attribute nodes. This pair is
implicitly passed to the string() function as per 

http://www.w3.org/TR/xslt#value-of
and its reference to
http://www.w3.org/TR/xpath#function-string

In short, string(foo), where foo is a node-set, returns the string-value
of the first node in the set. The string-value of an attribute node is the
attribute value.

The xsl template is apparently being instantiated twice, once for each
'tag' element, yet both times, the first node in that particular set
you've identified happens to be the same one.
