Hmm... Given a seed, rand() will create always the same sequences for that seed. But if the seeds changes all the time, you'll always get different sequences, as it's obvious. You'll get the same sequences only if you pass the same seed again, otherwise you'll get some other sequences. In practical use of rand() I have never seen what you're saying, though it's possible. But that doesn't imply that you'll get every time the same number consequentally in a sequence, that's very rare case if you use different seeds, very rare.
