At best, this sounds like a euphemism to me, and at worst, it seems like Amazon doesn't want to log such information. If Amazon cared to keep track of counterfeit returns, they'd make it an explicit option.
Honestly, it feels like Amazon is intentionally not keeping explicit records of the counterfeits they sell because of their potential liability and the fact that such records would make Amazon look bad in depositions.
That doesn't distinguish between "I ordered a book and got a plant mister" and "I ordered a book and got a stapled photocopy with greasy fingerprints."
