That's a weird one. Presumably both the two years of notice and this term are intended to ensure a publisher doesn't have to stop selling/throw away books it has printed in good faith under the existing copyright grant. But I'd be curious whether it will allow Penguin to continue to print new books (provided they're identical to the ones they've previously printed) or just sell the existing print run. Presumably even if they had permission to sell it as an ebook, they would have issues continuing to sell it as an ebook as formats and standards inevitably change.
