My understanding is that Amazon is not accounting for the royalties after they are returned from an author purchase and resold under terms other than the royalty free terms.
It's not that he wants to get paid for the unsold inventory, it's that he believes he doesn't get paid at all when they resell as new the used inventory he rejected and returned in quality control of his royalty free author purchase.
