Both stores featured stuff like this. A relatively small footprint for a "superstore", that did a lot by drawing your attention upwards to generate a sense of space. Every "department" had stuff like this, showing inventory 10-20 feet off the floor on very high shelves. Meanwhile the floorplan was rather claustrophobic and not somewhere you want to be on a busy shopping day. But if you needed to outfit a kitchen, bathroom, and a bedroom all on one trip, it was the the place to go.

Anyway, it's no surprise that there was stuff like this going on purely for show. Makes sense, actually. You wouldn't want staff restocking on ladders half the time.
