Comment (by pramsey):

 It's just that it's a change in behavior... I dunno.

 WRT your other question the answer is: it's a totally different code path.
 And yeah, it seems to be deep in the heart of GEOS. It's probably a
 similar short-circuit though (oh, hey, one side of my arguments is empty!
 i'm done!)
