One view is taken on the line. From this position, you cannot see the white-coated person sitting out in a chair on the sloping hillside to the left of the pond and the blind.
The second view is taken from a location toward the gallery so that you can see where the white-coat is placed. This person does have a function...he scents the point every 10 dogs. (The actual blind planter is hidden in the woods.)
The person in the chair certainly seems to attract many dogs once they approach a view where they can see him. There is much pull to the left (less angle and H2O to contend with overall) and the white coat contributes to that.
