Current() returns the context node from the context outside the
XPath expression, in your case the current node from the
document('foo.xml')/root/item node set, or the same as ".".
You can store the node you want to keep in a variable:

 <xsl:template match="form">
   <xsl:variable name="current" select="."/>
   <xsl:for-each select="document('foo.xml')/root/item">
      <xsl:value-of select="$current/@name"/>
   </xsl:for-each>
 </xsl:template>
