I don't know what processor you are using, but I don't believe that. 
It's not possible in XSLT! You didn't change the value, you only create 
a local variable.

Test it in the following way:

XML:

<root>
</root>

XSLT:

<xsl:variable name="teste" select="'um'"/>
<xsl:variable name="um" select="'um'"/>
<xsl:variable name="dois" select="'dois'"/>

<xsl:template match="/">
  <xsl:text>original: </xsl:text>
  <xsl:variable name="teste">
    <xsl:choose>
      <xsl:when test="$teste='um'">
        <xsl:value-of select="$dois"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$um"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  <xsl:text>after "changing the value":</xsl:text>
  <xsl:value-of select="$teste"/>
  <xsl:apply-templates select="root"/>
</xsl:template>

<xsl:template match="root">
  <xsl:text>value still changed? :</xsl:text>
  <xsl:value-of select="$teste"/>
</xsl:template>

You will see, that you didn't change the value of the global variable - 
or you don't have a XSLT-processor.
