I'm not sure I quite understand the point. The first photo tells the whole story, as it shows the real difference in DoF when shot near the same framing.

But why would anyone restrict themselves like that? No one would every think, "gosh darn it the Nikon 70-200mm lens maxes out at 200mm, so I must only shoot at 200mm EFL on my Olympus 40-150mm lens!". But I have read about people using longer focal lengths in order to get a shallower DoF and limit what is in the background of a portrait.

These are different formats and forcing oneself to use a framing from a different camera and lens is rather insane.

Why not?  If you want the background blur, you either increase lens speed, or increase focal length (while maintaining the same focal ratio).
