You're absolutely right. This article had nothing to do with measuring the size of the universe, only the Hubble constant, or rate of expansion. To measure the size of the universe, we must measure the general curvature of space. All of those measurements are so far within the margin of error of being completely flat. If it is completely flat, then the universe is truly infinite in volume and extent. If it turns out to have some curve, then it is just very, very, very big.
