From description, Use Coordinates evaluates the texture using target coordinates in the local space of the force field object. 2D is supposed to ignore the Z coordinate. Thus one would assume that if both are enabled, the force field effect would move with the force field object, and Z would be 0. However, instead first the 2D option projects points onto a plane passing through the global zero and orthogonal to the local Z, and only then the resulting point is transformed into local space. Z is not locked at 0, so procedural textures like Spherical Blend don't work as expected. To fix this, apply local transform first, and then just clear Z if 2D.
