I too would agree that the images are broken.  However, I have recently had
to update our internal TIFF library (not LibTIFF based) to understand
similar images from other vendors.  They are not common, but they do exist. 

We have chosen to initialize the defaults when READING Reduced Res images to
be the same as the main image instead of the defaults explicitly denoted by
the TIFF spec.  We always write all necessary tags when writing.
