The problem with having the start and end points the same is that the 
solution for the circle center is indeterminate.

In the case where the start and end points are different there are two 
possible circles (sometimes 1) which include the two points.  Which part 
of which circle is used is defined by the large-arc-flag and sweep-flag.

When the start and end points are the same, there are an infinite number
of possible circles which include that point.
