changing these to nodes since the larger building already exists

Hey Elliott! No, with some exceptions, I made these permission changes in the armchair style with aerial and street level imagery, and occasionally the plats. This block of Hargrove alley, however, was closed decades ago between Center and Monument, as you point out. With the available data all agreeing with that, I can only assume this was an oversight during a burst of enthusiastic editing, so I appreciate you already making the edit to reflect the correct private tag.
