Aha! Thanks, Mark. I had forgotten that the 7xx author/title entries are author/uniform title entries. This is most evident in music records, a bit less so for texts since so many texts don't get a formalized uniform title. (e.g. no a/t authority record).

Interestingly, my first example record gets a 740 for the second Twain title, but not an a/t entry. (Is there a rule that if there's only a title entry then it is assumed that the 1xx is the author? That sounds a bit prone to error to me.) Maybe it would be best to model the aggregate case using music records, since they probably do the best job of handling this case.

I don't know if these two types of aggregation would be treated the same in RDA or not -- but it doesn't seem to me that previous cataloging rules really handled multiple works in a single published item very well. For example, there isn't a way to have two uniform titles (right?).

Depends on what context you're referring to.  If you mean, say, a pair of 100 + 240 in a single record, then no.  But for a compilation of two works by different creators with a collective title (aka aggregate manifestation title):

Under AACR2:
100 1- Name01
240 10 Uniform title01
245 10 Collective title / Name01 and Name02.
700 12 Name02. Uniform title02.

Under RDA:
245 00 Collective title / Name01 and Name02.
700 12 Name01. Uniform title01.
700 12 Name02. Uniform title02.

If no collective title:

Under AACR2:
100 1- Name01
240 10 Uniform title01
245 10 Title01 / Name01.  Title02 / Name02.  [assuming Title01 doesn't match Uniform title01]
700 12 Name02. Uniform title02.

Under RDA:
245 00 Title01 / Name01. Title02 / Name02.
700 12 Name01. Uniform title01.
700 12 Name02. Uniform title02.
