Mark, I agree. The "choke" or "girdling" effect will take place (although to what extent is debated) if the metalic sections of the raceway are not bonded to the GEC at both ends of these sections.
I remember an informative post or posts from Dereckbc on this subject once, maybe he or one of the other engineers will chime in.
The bottom line is it is a code requirement as you posted.
