Fire stopping in basement

I think what the paragraph is trying to say is they require a solid <something> between areas. The areas are the vertical areas ("spaces") and horizontal areas. What needs to be done is to have a barrier installed (of of the "<something>") so if there is a fire in the basement (horizontal area) it can't easily travel up the walls (vertical area).
As noted in the permit information, it is easier to install this barrier before the (drywall for the) walls and ceilings is installed: you can get to it without the drywall in the way!

I believe the x 14" drywall pieces is the firestop. It is acting as a barrier to fire travel. The fiberglass insulation isn't part of the picture. A solid 2x4 cap/header would probably do the same thing. What they want is to have no "air connection" between the walls and ceiling. (The walls are the vertical spaces, the ceiling the horizontal spaces. Their use of "concealed" just means hidden from view; IOW behind the drywall.)

Best thing to do would be to have the city inspector approve the construction before the drywall is installed. (The electrical probably needs to be inspected before walls are put up also.) I think there are at least three inspections: (1) blueprints, (2) rough-in (framework [studs and joists] exposed, all the mechanicals installed [plumbing, electrical, HVAC]), (3) sign-off after drywalling is done but before occupancy.
