I wonder if Geoff had to go back and re-film his walk-through of the
overhead posters. First time round he was with the designer, now nowhere
to be seen. Might explain why it's taken almost a week to reappear.

No, I suspect he had plenty of unused original footage that he could use in
a new edit. He may even have realised when filming that he might need to
produce a different version like this.

Not so much "unused footage", as doing the walk through two separate
times.
