Well, I would argue that the term interleaved alone doesn't say
anything about the things that are interleaved. But I guess
split/grouped would be fine too if you want to avoid re-using
interleaved here.

The ECC strength doesn't say anything about the scheme used for ECC
bytes placement, and you might end up with 2 different schemes
providing the same strength, or the same scheme used for 2 different
strengths.
