Yes, they have different policies depending on what you purchase and whom you purchase it from.
Frequently with physical products Amazon is able to place the majority cost [they only lose out on their commission] of the refund onto the supplier. [e.g. If Amazon's fraud check fails to catch a fraudulent order, they push the cost of the chargeback onto the supplier if it is a FBA or MFN item. They also do this if their system screws up and merges multiple products onto the same ASIN even tho they are different colors or whatever.]
My guess is the vendor in this instance was large enough Amazon had to make a different deal where Amazon was the one eating the refunds if it was Amazon's error. The vendor blamed Amazon. Amazon couldn't even figure out I issued a chargeback and successfully disputed it for my money back.
