Typically this kind of setup works best when working independently. However in my experience doing similar setup in tech and other industries, many team mates have been grateful to work and learn from someone who otherwise would not work in their org or team.

It works other way around too, I would happily work in a team for much less pay if I can work with people I can learn from even if they do all the cool stuff.

Also I think he meant what kind of project he will work in not what all he will do in that project. Even if he did mean it that way, it is no different than in many regular roles where Senior ICs anyway pick and choose work they wan and junior members get the grunt work .
