Anime Architecture states that Hiromasa Ogura's backgrounds for this sequence were based on Takashi Watabe's LO, and explicitly credits cut 243 as Watabe LO (cut 3 in this post). Watabe likely did layout's for more of this sequence as well, but only Ogura's BG's for the first 3 cuts in this post are included in the book, and Watabe's involvement here is not specified further.

I'm unsure how involved, if at all, Watabe was with the movement for any of the cuts I'm commenting about, so I'm withholding tags for now.
