Special thanks to inaccurate translation. He prolly didn't contradict himself in Japanese.
I'm pretty sure in the first interview he refered to no role being strictly support, as in every class is either clearly tank, healer or DPS. A pure support role would be a class that does neither tank nor heal nor deal (considerable) damage. Even if Bard DPS is bad in comparison to others, it's still not as bad it would have to be for a pure supporter.
In the second he probably spoke more of support that is integrated in the current class lineup which differs a bit from class to class. Arguably Bard has more support to offer in that regard than say Black Mage, thus Bard leans more towards being a support class while still staying DPS in its core, even if a bit of that cake gets cut out and distributed among everyone else; you bet SE still counts this as contribution coming from the Bard.
