Understanding filtering order...

I was wondering if someone could clarify how I can selectively filter my XML
document using XSL.  I'm using the MSXML parser, fyi.  

My question deals with template match and apply-templates usage.  

I know the structure of my XML, so I'm filtering progressively down "layer
by layer" in a series of steps.  My question is this, if I use a series of
xsl:template defnitions, does the next segment that follows work against the
results of the its predecessor?  Being unclear on this makes it hard for me
to really know "where am I" at each filter, so my queries are no good I
think.  Someone showed me this approach yesterday, and I'm wondering when I
do the tempalte match="*" if I'm where I think (hope) I am.

I provided the XSL below for ref.  

Thanks,

Kris


<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
	<!-- filter by service type -->
	<xsl:template match="/">
		<xsl:apply-templates
select="Service_Def/Body/Services/Service[ServiceType='User']"/>
	</xsl:template>	
	
	<!-- filter by connection speed -->
	<xsl:template match="*">
		<xsl:apply-templates select="Service[ServiceType='User']"/>
	</xsl:template>
	
	<!-- filter by application version -->
	
	<!-- filter by product name -->
	
	<!-- apply filter by client program -->
	<xsl:template
match="Service_Def/Body/Services/Service[ServiceType='User']">
		<xsl:node-name/>=<xsl:value-of/>
	</xsl:template> 	
	
	<!-- apply filter by connection speed -->
	<xsl:template match="Service[ServiceType='User']">
		
	</xsl:template> 	
</xsl:stylesheet>
