Before r86885 and after r102224, these regions were decomposed without any coordinate transformation at all. Between those versions, the global transformation applied to all these regions. I think that behavior makes sense, but someone complained that r86885 changed behavior, so it was removed in r102224. Then someone ELSE complained that r10224 changed the behavior that THEY wanted, so this option is now added.
