My mum works with mentally disabled people and she once told me they try to exaggarate within the limits in order to get the funding a client needs. For example, they'll write down that a client needs full-time assistance during showering. A parent will then say to my mother, "But my kid can shower by himself!" My mother would say, "If your child was in an unfamiliar bathroom by himself, would he be able to shower? No. He'd need full-time assistance. So we're writing down he needs full-time assistance while showering."

They might have done something similar in your case.
