To nitpick, the wall itself is moving away at about one light-year per year. The photons that are not moving from our perspective because they are receding away from us at the speed of light will soon find themselves in a space where they are again moving towards us.
"we routinely observe galaxies that have, and always have had, superluminal recession velocities" -- Davis & Lineweaver.
