I have done this for both of my (adult) children. It does not cost anything but I have told them that anytime they use it to let me know in what shop and how much they paid.
I am not sure why it would be better? Unless his sister needs a credit card for other uses, I would think it is better for him to just use his credit card to pay for her Global Entry Fee. Credit card doesn't know/care who is getting the Global Entry, and Global Entry doesn't care who paid the Fee.
