The test will evaluate to true if the PB_ITEM has no child USER whose
string-value is the same as the string-value of the previous child USER, and
if it is true, it will then apply-templates to all USER children regardless
whether they satisfy this condition.

I suspect what you meant to write was something like

> 	<xsl:template match="PB_ITEM">
 	      <xsl:apply-templates
select="USER[not(.=previous::sibling::USER[1])]"/>

Which will apply-templates to every child USER whose string value is not the
same as the previous child USER.
