If-test of a sequence, why the need of `or`?

Question:If-test of a sequence, why the need of `or`?

Why do you need `or` in an if-test if say:

if `or`(seq(R[i]=R[k], k=1..i-1)) then
.......
end if;

If I run the test without the `or` (Boolean type logical, I know) it does not work.

Can anyone help me?
