The true Hi-Z (a.k.a. high impedance) mode is when pin is completely disconnected from the chip. This includes input buffer as well. Nevertheless, some hardware may not support that mode and they are considering input only as Hi-Z, but more precisely it is an equivalent to that, in electronics it's basically "an antenna mode". Sligthly correct documentation to take the above into consideration.
