The Australian Arbor Age October - November 2007 edition page 61.
I have scanned the page and blown up the pic and added a red line as to where the correct cut should be made.
If you look at the pic carefully you'll notice that all his lines with the green arrow heads pointing to the BBR are out by the same amount as his white cut line. Looks like the whole overlay of his "paint shop" is out to the left by the same amount and if it were all moved right by the few inches then it would line up, except that his cut needs to be a tad more acute (closer to trunk at bottom).
That union he has photographed is called a collarless union. The way you cut them is mirror the BBR angle to the trunk on the other side of the BBR. I put a red line in the blown up pic to show.
Not a good typo, could mean stub cuts and no understanding of the 3 cuts I speak of often.
Pruning cuts - collar, collarless and co-dominant
