Well, I'm afraid you possibly misread what Araki said on Hermit Purple.

Hermit Purple is infact a stand, however, it is the manifestation of Hamon as a stand, as Araki puts it.

And Jonathan does infact have a stand...

It is seen as the variation of Hermit Purple that DIO briefly has, Hermit Purple 2 as we call it. It's ability is the same as Joseph's Hermit Purple, however it does not need to destroy the camera in order to produce the psychic photos, so it can be considered a better Hermit Purple.

To support this, it's known that DIO originally had a hard time adapting to Jonathan's body, since DIO had his body divided in half, one half being stronger and fully vampiric, the other being weaker, taking more time to heal than the other. It's possible that when DIO was pierced, that was still the case, and recognizing DIO as two people, the arrow gave Jonathan and DIO their respective stands, but Hermit Purple 2 eventually faded away as DIO gained full control of Jonathan's body.
