Actually I don't see that the authority record contains any explicit instruction at all about coding. The scope note simply says "Here are entered books set in a type size larger than normal for the benefit of persons with impaired vision, as well as works about such books." The coding (655 vs 650) is determined by the encoding standard, and it's quite clear from MARC that 655 is used, as Adam says below, for examples of a term; the MARC format is perfectly clear that 650 is used for works *about* the term. Just because LC or others have been in the habit of confusing these two fields and coding genre/form in 650 instead of 655 doesn't change the standard definitions (which have been around since the early 1980s).

It is only redundant if you index your 655s in the same index as the 650. If you have a separate genre/form index for terms describing what something IS rather than what it's ABOUT, then users would expect to find large type books in the genre/form index when what you have is an exemplar of one. The LCSH scope note notwithstanding, really the only correct coding for an exemplar of a large type book is 655. 650 really ought to be reserved for terms describing what something is about.
