AFC,
A half hour conversation with TEPaul is the equivalent of leaving a voice mail message with the rest of the world.
I viewed Bill Coore's remarks a little differently.
Bill stated that the developer, Roger Hansen, gave him the freedom to design what he chose, and as such, Bill felt that he'd rather not dictate shots, but rather, have them evolve through natural progression or choice.
While there are wide playing corridors, there are prefered lanes and lanes to be avoided within those corridors.
I think Bill wanted the golfer to craft and/or define his shot rather than have the architect do it.
With respect to framing, they deliberately cut the woods further back near the greens, just to avoid the feel of framing.
Bill indicated that they defend the golf course, through design from the green back to the tee, and by providing great diversity in the greens it leads to greater diversity in the approaches and recoveries.
I understood Bill to say that he likes to combine that philosophy with the presentation of awkward lies through the green in an attempt to enhance variety, uncertainty and difficulty in selecting an approach or recovery.
