The GNU tar format originates from a non-compliant variation of POSIX ustar, which appears to have been inherited from John Gilmore's pdtar. And according to pdtar's source code, draft 6 of POSIX.1-1988 was the reference used to implement ustar. Thus, it would be interesting to peruse draft 6, and see if the variations stem from later changes to ustar, or ambiguities in the draft's wording, or what.

I do have a draft copy standard of 1003.1 Issued April 1986.  I can't find where there might be an indication of which draft it is, but it is a published copy with a nice dust jacket (pictured here : https://wiki.tuhs.org/lib/exe/fetch.php?w=200&tok=e9832c&media=publications:1986_posix_draft.jpg), much nicer IMO than the final perfect bound copies that came out.

Section 10 concerns the "Archive/Interchange File Format (TAR Format)".  If this is the specific draft you are referring to, I'll gladly give this section an expedient scan.
