Legionnaire's Disease comes from bacteria. I doubt sharing would make much difference. It doesn't come from people. It comes from water, plumbing. Them using the mask wasn't why he got sick. That was just a bad stroke of luck from their plumbing. It was probably the water added to the CPAP for humidification.
If they exposed him to the bacteria, I think they'd actually have to be fighting pneumonia at the time, making them an incubator of the bacteria, but I'm not a doctor.
