Yes, but she’ll have to put up with some obnoxious nurse lecturing her about the ills of formula every damned time she asks for a bottle. Hospitals can be miserable enough places without such crap.
On paper, yes, she'll get a lecture re: formula. In practice, the first time she asks, some nurse will ask her to sign some form saying that the nurse talked to her about formula, and that's the last she'll hear about it.
Besides, as things stand now, plenty of obnoxious nurses lecture new mothers about the benefits of formula (by the time she left the hospital, my wife was ready to smack the next nurse who told her how much easier a bottle would be).
