Comment (by nicklas):

 I looked at this again and tried to figure out the issue. But what you
 write doesn't really make sense. Last argument is true by default. If the
 third argument is true by default or by setting it you will not get
 aligned lines in your polygones. That is because then the function will
 not touch the first and last vertex. That is default since it otherwilse
 will break any network of linestrings. But if you set the last parameter
 to false it will not preserve the first and last vertex and it should give
 you what you probably expect.

 Please recheck and see if there is an issue and I will look into it, or
 set this as invalid.
