Why searches gives us a 1 in 2^7 chance of hitting? not all?

Tell me more...

code :

net.spy.memcached.KetamaNodeLocator

    public Iterator<MemcachedNode> getSequence(String k) {
        // Seven searches gives us a 1 in 2^7 chance of hitting the
        // same dead node all of the time.
        return new KetamaIterator(k, 7, getKetamaNodes(), hashAlg);
    }
