Is canting the fairways and greens in the same direction a meaningful architectural device to add to the challenge of an approach shot?

Most definitely. I believe both Mackenzie and Ross wrote about this too. As a corrollary of this, there is also the use of slopes and doglegs to encourage two different shape shots on the same hole - for instance a dogleg left that encouages a draw from the tee, and a canted green that invites a fade, and of course the opposite alternative. I think it is a terrific use of natural terrain for strategic purposes.
Locally, I reviewed Callippe Preserve in Pleasanton, CA and wrote about this exact phenomenom. The first hole is a downhill dogleg left with a green guarding the inside of dogleg. The fairway is canted in two directions. The person who bales right on the tee shot is left with a downhill, sidehill lie that encourages a draw - but the green is canted from right (high) to left (low). A shot that does not fade from the right side of the fairway is going to find it difficult to hold that green. Conversely, a shot that hugs the fairway bunker left will not only find an excellent line of attack, but also a fairway cant that encourages a fade. Wonderful hole on a terrific golf course designed by Brian Costello.
