This is not true. As far as I know, the code uses the interpolation as
suggested in the original NEB paper. This interpolation is kind of cubic
interpolation, which uses the information also from the forces (=slope)
provided by the code. According to my experience it's rather good (see
the appendix in G. Henkelman, J. Chem. Phys. 113, 9978 (2000)).
