IIRC the compulsory reporting intersections were the filled in triangle.
Non-compulsory were triangles.
Compulsory wasn't required once you were in radar contact. Reaching a
previous clearance limit and the final approach fix were compulsory too.

The stock clearance into HPN from the POU area is IGN V157 HAARP. It's
been that for as long as I've been flying around here. Recently, they've
started issuing IGN V157 VALRE V157 HAARP, which boils down to exactly the
same thing (VALRE is just a bend in V157).

Today, I asked the controller about it. His response is that he just
reads
what gets printed on the strip, and they've been wondering the same thing
in the Tracon :-).

Does anybody have any idea why the ATC computer would be generating
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.
