Here is a second attempt, more like what I wanted to implement

<xsl:stylesheet
  version="2.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:xs="http://www.w3.org/2001/XMLSchema";
  exclude-result-prefixes="xs">

  <xsl:param name="inp1" as="xs:string" select="'input1.xml'"/>
  <xsl:variable name="input1" as="element(input1)" 
select="document($inp1)/input1"/>

  <xsl:output method="xml" indent="yes"/>

  <xsl:template match="input2">
    <output>
      <xsl:apply-templates select="w[1]">
        <xsl:with-param name="skipped" select="0"/>
      </xsl:apply-templates>
    </output>
  </xsl:template>

  <xsl:template match="input2/w">
    <xsl:param name="skipped" as="xs:integer"/>
    <xsl:variable name="pos" as="xs:integer"><xsl:number/></xsl:variable>
    <xsl:variable name="match" select="$input1/w[$pos - $skipped][. = 
current()]"/>
    <w n="{if ($match) then $match/@n else 'skipped'}">
      <xsl:value-of select="."/>
    </w>
    <xsl:apply-templates select="following-sibling::w[1]">
      <xsl:with-param name="skipped" select="if ($match) then $skipped 
else $skipped + 1"/>
    </xsl:apply-templates>
  </xsl:template>

</xsl:stylesheet>
