Why does that make the study meaningless? I don't think I've ever read a study that says "homeschooling only works if you're white" or "public schools are only for the poor". Are we supposed to believe that the effectiveness of education is dependent on skin color?

No, its because people who are home schooled are more likely than the average student to be in classes (white, rich) that already do well in school, yet they still compare their scores to the general population.
