We did answer that.  The short answer is, they're not directly related.

There was no UNIX System IV.

UNIX System III was the commercial name for USG UNIX 3.0 and UNIX System
V was the commercial name for UNIX 5.0.  Because of the marketing hoopla
about UNIX System V being the "standard" UNIX, further commercial
releases retained the name "UNIX System V".  This is expected to continue.

There was a USG UNIX 4.0 (also 4.1), which some government sites obtained
but which wasn't generally available for commercial license.
