Or possibly when the precursor to the binder was developed that long ago, whoever wrote this section figured with a 44 character DSN being the longest available, they padded it with 20 bytes to make sure it was plenty long. Then when Unix-style path names came along later, whoever added the path capability decided to not increase the length in order to not take a chance at breaking anything?

Gil mentioned the "DATA SET SUMMARY" section. I presume his use involved the file system. For a data set, the lines in that section would not come close to reaching column 84. For example, DDNAME CONCAT FILE IDENTIFICATION LPALIB 01 SYS1.LPALIB SYSOBJS 02 TESTUSER.OBJS I would guess that many who read the append did not realize that the original post related to presentation of a "long" path name. I know that I did not. Regardless, for whatever reason, when the binder was developed going on 25 years ago someone implemented "put 64 columns of path name info per line". Maybe they thought that was a reasonable amount, maybe they wanted a power of two; I have no idea. This has apparently not been an issue to anyone.
