Then you *don't* need the loop at all:

  <xsl:template name="getOrderSource">
    <xsl:choose>
      <xsl:when test='/ns0:Transaction-850/ns0:Loop-N1/
                      ns0:Segment-N1/ns0:Element-66 = "21"'>NAEDI</xsl:when>
      <xsl:otherwise>NAEDIBrokerage</xsl:otherwise>
    </xsl:choose>
  </xsl:template>

In XPath when you address a set of nodes as an operand in a test, the 
test is repeated for every member of the node set until either a 
true() value is returned by any member (you aren't told which), or 
until the node set is exhausted and a false() value is returned.

I hope this helps.
