ELI5: The difference between "antibiotics important to human medicine" and "antibiotics"

I saw Pizza Hut come out with a press release titled "PIZZA HUT PLEDGES ALL CHICKEN TO BE RAISED WITHOUT ANTIBIOTICS BY 2022" but the release goes on to say, "...commitment to serve chicken raised free of antibiotics \*\*important to human medicine\*\* (per World Health Organization) by 2022.

Some antibiotics have major negative sideeffects when used on humans, so they won't become important until a disease with worse sideeffects than that becomes resistant to everything else. 

Someone had a great idea for how to seem like you're doing something to save the world (and which may in fact help) without harming profit margins.
