Explained another way......
The ISS (and its occupants) are falling to earth.
They are also traveling at around 5 miles per second over the Earth.
In that second, the curve of the Earth means that its surface has "fallen" another five miles away from the ISS.
The ISS is constantly falling towards Earth, but the Earth is constantly falling away from the ISS.
