title: Clearcase UCM - Cross delivering vs. delivering upwards?
body: <p>We have two Clearcase UCM streams in a hierarchy at the same level (i.e. same parent stream).  If the two child streams are both rebased to the same parent baseline, does that mean that</p>
  
  <ul>
  <li>Delivering the activities of both streams up to the parent (one, then the other)</li>
  </ul>
  
  <p>Would be equivalent to:</p>
  
  <ul>
  <li>Delivering the activities of one child stream to the other child stream, and then simply delivering the one child stream to the parent</li>
  </ul>
  
  <p>Is this in fact true?  It seems it should be, assuming any manual/user selected merges for all deliveries are made in the same way.</p>
