It answers catalogue volume: a new season, a marketplace launch or a restyle of everything already live. The job is less about any single image and more about the batch holding together, with the same model, light, crop and colour on every product.
Most bulk runs fail at the edges. A few products come back in the wrong colour, with a changed logo or a missing pocket, and in a batch of hundreds those slip through unless someone checks. That is why batch work needs a review step built in, not bolted on at the end.
