With the option it processes the elements in the order that they appear 
in the input file.

Without it, they are processed in an arbitrary order. In this case you 
are lucky as the arbitrary order happens to work for you. With a 
different tile extract or after a few edits you may be unlucky again.

The reason that I think that preserve-element-order should always be on 
is that it makes the output consistent.
