> It might also mean that he doesn't personally have rights to publish it himself, if it depends on copyrights somebody else holds and only licensed to Penguin, not him.

The AA Milne estate still has a copyright on Winnie the Pooh for several more years and stated in one of the letters that they are "not in a position" to grant him a license (exclusive contract with Penguin?).
