There is more than one emotion that can be used for reward. Nobody has argued against that. There can’t be more than one unless there are separate neurological mechanisms.
The important thing is that not every emotion useable for reward is good. There is no way they could have possibly figured that out from that study. That part was either from introspection or someone misinterpreting the study.
Knowing that ‘wanting’ and ‘liking’ use distinct neurological mechanisms is useful. (Using the term ‘qualia’ - not so much.)
