Single point line (two verteces on top of each other) = NO POINT DRAWN

Code is currently:
with TOpenGLAPIVersion110 do
begin
// render ray
glLineWidth( 1 );
glBegin(GL_LINES);
// begin of ray is dark gray
glColor3f( 0.25, 0.25, 0.25 );
glVertex2f( mRay.Start.X, mRay.Start.Y);
glColor3f( 0.75, 0.75, 0.75 );
glVertex2f( mRay.Stop.X, mRay.Stop.Y);
glEnd();
end;
When x,y,z coordinates of Ray.Start is equal to those of Ray.Stop OpenGL does not draw a "point".
Why is this ?
Are the end points of lines "not inclusive" ?
Bye,
Skybuck.
