Not true. To the extent that it is fair use to digitize a work for various purposes, it is also fair use to keep the original. It is only if they wanted to resell the original that they would have to delete their digitized copy. The reason they are destroying them because removing the binding is the most efficient way to scan them, they have no use for the originals after they have been scanned, and don't want to spend money storing them.
