That’s exactly it actually. I think the technical term they use is “maximize your opportunity to decide to make other purchases” but the concept is the same, to make you walk through as much of the store as possible to see as many different items as possible so that maybe you’ll decide to buy something else. That’s why all that stuff you want to get by “surgical strike” (milk, bread, produce, meat, liquor, deli, pharmacy) is spread all around the perimeter of the store, if you want more than 3 items on that list you’ll wind up walking around the entire store.
