I agree, the softness at 0.5 one is a completely different color! Fresnel is implemented in the tutorial as a subtraction of color from the texturemap. The bottom right sphere has had a heap of color removed, and is darker than the rest - it has overpowered the texture. The sphere on the left has a much finer level of spots that have been removed - and won't impact the texturemap so much. The 3 spotted spheres also look like they still have some specular in them.
