Subject: [ggl] Quick question about bg::difference

I have a question about the difference algorithm.

template<typename Geometry1, typename Geometry2, typename Collection>
void difference(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection)

What happens in the case that the 2 geometries are disjoint? So far in my test cases it seems that in disjoint cases it will always return the second geometry, is this guaranteed ?

Thank you
