A better question would be, why would you do an online survey of only black men, if your goal is understand "the unique challenges of brain health and cognitive decline faced by Black men"? Surely you would want to leave it open to at least white and hispanic men too, to at least try and see if those challenges are in fact 'unique' and have some sort of baseline or comparison? And it was an online survey of self-reported measures recruited by an existing survey service (CloudResearch), so they were not limited to an existing sample of only black men - they went out of their way to restrict the sample.
It's an analysis of cognitive decline from "active coping and grit". The study is being done exclusively on a black cohort, it appears from their Background, because these studies have already been done on white cohorts and they have the data available already to do the comparisons. I'm not a scientist, feel free to correct me, someone, if I'm misreading this.
Is the use of the data appropriate/applicable to what the linked article is suggesting? Probably not.

Assuming that you did not want to make the simple statement that their meanings or referents are different (because people usually don't doubt that), I can give you a counter example:
With all the studies finding correlation between smoking and lung cancer it indeed turned out that correlation was in fact causation.
Also wow, sharing my data with 1600 "partners"
