So both of my Release 5.0 User's Manuals have the Bell logo on the front and no mention of the court order to cease using it.  Likewise, all but one of the System V related documents I received recently contain a Bell logo on the cover next to Western Electric save for the Opeartor's Guide which curiously doesn't exhibit the front page divestiture message that other documents missing the Bell logo include.  Furthermore, the actual cover sheet says "Operator's Guide UNIX System Release 5.0" so technically not System V. In fact, only the User's Manual, Administrator's Manual, Error Message Manual, Transition Aids, and Release Description specifically say System V, all the rest don't have a version listed but some list Release 5.0 on their title page.

Until the Operator's Guide and this auction link, I haven't seen any "Release 5.0" branded stuff without a Bell logo, and before I bought the System V gold set, I hadn't seen System V branded stuff *with* the Bell logo.

The covers are all printed, I can't see any indication that a bunch of 5.0 manuals were retroactively painted over nor that any System V manuals got stamped with a Bell post-production.  What this means is "Release 5.0" documentation was being shipped post-divestiture and "System V" was being shipped pre-divestiture.  If Release 5.0 was publicly sold as System V, then what explains the post-divestiture 5.0 manuals floating around in the wild, and vice versa, if USG couldn't effectively market and support UNIX until the divestiture, how is it so many "Release 5.0" documents are floating around in well produced commercial-quality binding, both pre and post-divestiture by the time the name "System V" would've been king.  Were they still maintaining an internal 5.x branch past System V that warranted its own distinct documentation set even into the commercial period?  This period right around '82-'83 is incredibly fascinating and I feel very under-documented.

For at least the User's Manual and Administrator's Manual there is
another version.

"Release 5.0, announced in October 1982."

"AT&T's divestiture in 1983 allowed UNIX to compete in the commercial
market place and on 1st January 1983, Commercial System V was announced.
As it was identical to Release 5.0, this was the first time that current
version of UNIX in the Labs was licensed outside."
