What made more sense with your previous understanding?

When I think of a "sector" I think of a block of airspace, not a set of
arrival points or routes.

Hmmm...well, the procedure requires you to start at the fix that defines the NoPT
terminal route. Where is the mystery in that to the designer?

I am cleared to a fix, and cleared for the approach. The fix I am
cleared to (especially in a GPS world) is not necessarily "the fix that
defines the NoPT terminal route" but may be a fix that is on the
approach. It's not on a NoPT terminal route, but it is aligned with the
FAC and I'm at an appropriate altitude.

I suppose the designer didn't design it for that, but sometimes it's
used that way.
