No. What he says is:
Buy any book -> Open ASCM in ADE 2.x -> Old DRM -> Works with old & new devices and ADE 3.x.
Buy any book -> Open ASCM in ADE 3.x -> New DRM -> Works with new devices only.
So I forsee that many people who don't know much about DRM and stuff might update to ADE 3.0 ("Hey, there's a new version, why not?"), buy a bunch of books, download them, and then find out they won't work with their old reader anymore.
I do not know if it's possible to remove ADE 3.x, replace it with ADE 2.x and then redownload the book by using the ASCM-file with ADE 2.x. If it's not, then the customer will have unknowingly scrambled a book into an unusable state, at least until he gets a new reader.
