You’re using circular logic. If it was just that three days a week the TE continues on to LAX as its own full train (which it is not), then there would be no need for the 421/422 numbering on top of the standard 21/22. It’s the fact that only certain cars continue past SAS as part of the Sunset, that requires having 21/22 AND 421/422.
I have to agree with cpotisch. If the
Sunset Limited was moved to a daily schedule NOL-LAX (Oh, to dream!) and the current situation with the through cars to Chicago via SAS and D-FW continued unchanged, the
Texas Eagle would still have to operate as Trains 21/421 and 22/422 to distinguish between the cars which operated differing itineraries. Think about it: The extra coach which operates CHI-STL runs 7 days a week, and it has its own "train number" (321/322).
