Good question. I'm not familiar enough with those two sets do give a conclusive answer, but I can say this:
If the cards are truly identical, then no, they do not get a separate listing. A note would just go in the User Comments or Release notes section of the Rudy Farms set stating that the five legends cards were also distributed as a set from RB Rice.
I see that the two are not differentiated in Becket annual #5,but that doesn'tnecessarily mean there isn't some difference between the two releases. I'll ask around. I know a couple people who may have gotten the RB Rice set from the original source.
