If I understand correctly, the implicit return value of remove_iptables()
is the return value of its last command, which is the included for-loop.

And the implicit return value of the for loop is the return value of the
last command run inside the for-loop. Which is the test whether $found
is one. On my system $found is zero.

So the test "fails" and remove_iptables() returns non-zero.
