I think the problem there is that it is just poorly explained.
Take for example the attached program that compares "normal" and "kashida"
'Raħīm' taken from [1], you'll get:

c1 = c2
c2 = c1

meaning that "normal" and "kashida" are the same string. So, probably that
phrase should read something like: "If an application calls the function to
create a sort key for a string containing an Arabic kashida character, the
function will ignore that character and no sort key value will be generated
for it."
