I'd still classify what they're doing as DevOps type of work. It just happens to be a wider spectrum of things vs their usual "write YAML" in that 1 role. Sounds like the original poster found a more enjoyable role with the same title?

I do a ton of different things every day and have been for the last ~10 years, all in the neighborhood of DevOps'ish type of tasks. I've written about 120+ of those tasks at https://nickjanetakis.com/blog/120-skills-i-use-in-an-sre-pl.... I do agree, it is fun to mix it up in your day to day (IMO).
