Does anybody have any idea why the ATC computer would be generating=20
clearances with the same airway mentioned twice?

In a non-radar environment, as I recall from the days before radar,
a non-compulsory reporting point becomes compulsory if it is mentioned
by name in a clearance.

I'd guess ATC *really* wants to know when you pass VALRE,
even if the radar goes out of service.
