There's no direct relationship between the form of the XPath expression
used in a select attribute and the form of an XSLT pattern used to match
the nodes.

a node might be selected by 
select="foo" or 
select="parent::foo" or 
it really makes no difference. The criterion for deciding whether a node
is matched by a particular pattern only involves the node and its
location in the current document, the expression used to select the node
is simply not consulted during the matching process.

select="child::foo selects the parent of the current node, 
 match="child::foo" asks if that node is the child of anything.
So unless you find it surprising that something can both have a parent
and be a parent, I'm not sure what is surprising here?
