I believe, and someone please correct me if I'm wrong, it is because the higher borrowing rate would eat into the return of a borrowing portfolio which creates a kink in the line as opposed to a straight line. I assume brafique referred to it as a reverse kink when compared to one of the chart in econ (demand curve for an oligopoly maybe?) which goes in the other direction.
