[r-t] Union Doubles versus Triples

[Don Morrison]

(Truth in advertising disclaimer: this query is actually prompted by
an observation from Eddie Martin elsewhere, but it stimulated my
curiosity sufficiently I thought I'd ask here.)

Am I correct in believing Union Triples is not related to Union
Doubles?

If so, how did this situation come about?

In the 1980 CC Doubles collection the doubles method was named "Union
Bob Doubles". As of the latest CC Decisions (E)D.2 it's just called
"Union Doubles". When was the change made, and why?
