My speculation: this is based on a change under RDA:

AACR2 25.2B: Do not use a uniform title for a manifestation of a work in
the same language that is a revision or updating of the original work.
Relate editions not connected by uniform titles by giving the title of the
earlier edition in a note in the entry for the later edition (see 1.7B7,
2.7B7, etc.) and by making an added entry as appropriate (see 21.30G).

RDA If the work is presented simply as an edition of the
previously existing work, treat it as an expression of that work. Use the
authorized access point representing the previously existing work [as main
entry]. If it is considered important to identify the particular
expression, construct an authorized access point representing the
expression as instructed at 6.27.3.
