Flip in Constrained Delaunay Triangulation

HI,
I see that the Flip method flips an edge even if the neighbouring faces form
a non-convex quadrilateral. See the image below:

Is this the expected behaviour? Of course, I can avoid calling flip() by
checking if the two faces form a non-convex quadrilateral.
