It was the other way around.
"The original intent had been to call it the 5BSD release; however,
there were objections from AT&T that there would be customer confusion
between their commercial Unix release, System V, and a Berkeley release
named 5BSD. So, to resolve the issue, Berkeley agreed to change the
naming scheme for future releases to stay at 4BSD and just increment the
minor number."
