Oh, you can have multiple layers of error correcting coding.
Eg Google stores data internally with something like Reed-Solomon error correction, but they typically have two independent copies.
So they have repetition code at the classical nano-scale, then Reed-Solomon error correction at the next level, and at the highest level they apply repetition again.
There's nothing confusing about this, as long as you are careful to make sure that your listener knows which level you are talking about.
> Repetition codes have a very clearly defined meaning in communication theory, using them to mean something else is very confusing.
OP used them exactly with the orthodox meaning as far as I can tell.
