I suggest to first do some renaming to make regionOfB the prefered one.

regionOfB => maybeEmptyRegionOfB
regionOfNonEmptyB => regionOfB

Then track easy units like Line or Document

maybeEmptyRegionOfB Line => regionOfB Line
maybeEmptyRegionOfB Document => regionOfB Document

Finally track the last maybeEmptyRegionOfB carefully.

Cheers,
