AFAIK the airline can require that someone travel with their own personnel assistant if the person would be totally unable to take care of themself in an emergency or use the bathroom without help, etc. FAs are not required/expected to help with passenger's bathroom hygiene although they do help to get a. mobility-challenged person to the lavatory using an aisle wheelchair if necessary.
I suspect that the discussion earlier in this thread was about the onboard aisle wheelchair, for passengers who cannot walk short distances.
