Comment (by mdavis):

 Pretty likely that JTS gives the same result.

 There's a lot of heuristics in the buffer code, intended to give stable
 and correct results for all of the various ways in which it can be
 parameterized (but with priority given to the primary use case of round
 buffers).  It might be possible to improve the heuristics to get better
 results in this situation, but it will require either extensive testing to
 ensure no regression in all other buffer situations, or a different code
 path provided for just Single-Sided Buffer.
