Comment (by dbaston):

 I think the tickets referred to in the UnaryUnion comments suggest that
 the cascaded union helps robustness by unioning nearby lines together
 (which supposedly helps because of common bit removal.) I think it's
 becoming off-topic for this ticket but we can discuss at
 https://github.com/libgeos/geos/pull/213
