Don't looks Hashimoto corrections at all, but more than probably yes for the two other scenes of the episode: https://www.sakugabooru.com/post/show/163560

This scene is confirmed to be Kurihara while the KA list is fully outsourced, since he is the director I guess he just wanted to redo the scene by himself.
