hernesheir commented on the word saddle point
In mathematics, a saddle point is a point in the domain of a function of two variables which is a stationary point but not a local extremum. At such a point, in general, the surface resembles a saddle that curves up in one direction, and curves down in a different direction much like the profile ofhorse saddle or a mountain pass, or col.

I think that you might find the behavior of a Hessian in the vicinity of a col to be pretty tricksy.
