That's all perfectly legit, but note that there's nothing about that
that requires the processor to run them in parallel. And XML Calabash
won't (at least not yet).

<p:identity>
  <p:input port="source">
    <p:pipe step="branch-1" name="result"/>
    <p:pipe step="branch-2" name="result"/>
  </p:input>
</p:identity>
