Whirly,
I couldn't agree more.I was taught the same procedure,by an English instructor, at a US flying school and it helped enormously. When I came home, local pilots I flew with commented on my habit of continuous "eyes outside" and regular traffic calls. I make a point of getting passengers to keep their eyes open and call out any traffic, especially if it appears that I haven't seen it. I've had enough close calls to appreciate the value of a good look-out and, reinforcing the original poster's point, of good SA.
regards
TDD
