First positional grouping

This is my first attempt at positional grouping and I'm almost there.
I'd like to transform


<!-- source.xml -->
<root>
<var VGID="AA" label="Families"/>
<var label="Fathers"/>
<var label="Mothers"/>
<var VGID="AB" label="Relatives"/>
<var label="Inlaws/>
</root>

into
<!-- desiredResult.xml -->
<varList VGID="AA" label="Families"/>
        <var label="Fathers"/>
        <var label="Mothers"/>
</varList>
<varList VGID="AB" label="Relatives"/>
        <var label="Inlaws/>
</varList>

by promoting all <vars> with a @VGID. I'm following the example at
http://www.dpawson.co.uk/xsl/sect2/N4486.html#d4085e229
Using the following style sheet,

<!-- myStyleSheet.xsl -->
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
        <xsl:apply-templates/>
</xsl:template>

<xsl:template match="root">
        <root>
                <xsl:for-each select="var[(_at_)VGID]">
                        <varList>
                                <xsl:apply-templates select="@*"/>
                                <xsl:for-each select="following-sibling::var[
                                          count(preceding-sibling::var[(_at_)VGID][1] | 
current()) = 1]">
                                        <xsl:copy-of select="."/>
                                </xsl:for-each>
                        </varList>
                </xsl:for-each>
        </root>
</xsl:template>

<xsl:template match="@*|node()" priority="-1">
        <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
</xsl:template>

</xsl:stylesheet>


I get this result:
<!-- ActualResult.xml -->
<root>
        <varList VGID="AA" label="Families">
                <var label="Fathers" />
                <var label="Mothers" />
                <var VGID="AB" label="Relatives" />
        </varList>
        <varList VGID="AB" label="Relatives">
                <var label="Inlaws" />
        </varList>
</root>

which has an extra third node under the first <varList>.
Can someone help me get rid of the extra node? It should
be a matter of just amending the XPATH in the inner for-each.
