I just noticed this detail in the manga and it's confusing me. I always heard people say that Hamon became obselete once Stands were introduced because hamon can't effect stands. Right? Well...

During the short fight between DIO and Joseph in the rooftops, we see DIO feels threatened when he's about to punch Joseph but realises he's hiding Hamon-charged Hermit Purple under his shirt. But only now did I realise It wasn't DIO's punch, it was the World's! Does this imply that Hamon can hurt stands? Or is it just that the Hamon conducting into the World would also conduct into DIO (since effecting the stand = effecting the user)?

I'm guessing it's the later. Thoughts?
