Yeah, that's probably--and hopefully--what they meant. The whole purpose of the standard mode is to make balancing a bit simpler and to reduce the (to-be-balanced) cardpool. Balancing the whole cardpool, as it's happening now, is unreasonable given the introduction of standard.
This means that dusting old cards is better postponed until they get nerfed or buffed.
