Qualitatively, it makes sense. Generalized Born is a generalization of
the Born solution to the Poisson equation
(
http://en.wikipedia.org/wiki/Born_equation). It defines an "effective"
radius, which is basically the average distance from the charged atom
(a.k.a. the *ion*) to the surface of the dielectric boundary (with the
solute being a region with a low dielectric constant and solvent being a
region with a high dielectric constant).
In this case, the effective radius will obviously depend on its
immediate surroundings, since those surrounding atoms will exclude the
solvent from a larger region around that central atom. So removing a
residue between two atoms will affect the interaction between those two
atoms through its effect on their effective radii.
