No, it is the position in "the context node list" of the node matched by the
pattern, not of the node matched by the <xsl:template> containing the
pattern. You can work around this by using a variable:

<xsl:variable name="position-before-me" expr="position() - 1"/>
<xsl:??? select="../*[position() = $position-before-me]"/>

But it is better to:

<xsl:??? select="from-preceding-siblings(*[1])"/>

See section 6.1.1 (Axes).
