I get:

       ____+_____
      /          \
     *            *
   /   \        /   \
  x     +      x     +
      /   \        /   \
     y     z      y     z

Aren't you only DUP'ing the result so far?

If you DUP then change the value of z before +'ing, you would get the same result as it's not really two trees being evaluated...
