The justification by Apple is that it keeps the concentricity between window corner and the red/green/yellow window controls. Which, as you may notice, it does.
It's wrong though, because the window is the higher element in the hierarchy (container) and should not be affected by what is inside. It creates a larger inconsistency than the "consistency" it supposedly brings.
