If you reuse them, then it's not a one time pad any more, is it?

Yes, it's well known that two-time pads are very vulnerable in ways that one time pads are not.

They are still one time pads, just incorrectly used.

Even if the cryptography is sound, you also need to ensure that no user error can happen.
