It suggests this by stating a fall of 5m from a height of 10m produces the same force as a fall of 20m from a height of 40m (both fall factor 1 falls).

The two falls actually don't produce the same force. The farther fall generates much more force, but there's more rope to handle that force in direct proportion. When people say, "both falls generate the same force," what they actually mean is that the top piece feels the same force in both falls, because the longer length of rope "absorbs," more of it.
