Not all that odd really. TIFF files commonly include a thumbnail, but the image data in the rest of the file can be encoded in many different ways. CMYK/RGB, JPEG/ZIP/LZW compression, groups of R/G/B pixels, planes of R then G then B, and lots more. TIFF is a very flexible file format that was introduced by Adobe years ago, and was used as a holder for RAW data by many early cameras. The RAW files produced by the EOS 1D and 1Ds (the Mk.I bodies) and by the Kodak DCS SLRs are all TIFF files, and all behave as you've described.
The RAW conversion software knows how to decode the RAW data, but at least the thumbnail and the basic EXIF data are in "standard" formats.
