Yes, but the article is indeed unclear about this. In particular this line:

>The farther away that galaxies were, the faster they were receding.

This is already the case in Hubble's law, which says that the velocity is proportional to the distance. Hubble's constant is the proportionality constant and thus the expansion rate.

Riess found that the Hubble constant is not constant. Instead, the expansion rate is increasing over time.
