Why are non-Henford sims obsessed with talking about the Henford villagers?

That have happened to me once so far, I think the game confuses a sim (in your case) Salim Benali for a Henford on Bagley sim. In my case it was a sim who had visited the bar in Finchwick when I was playing another family there.

I really hope that they did not add a gameplay mechanic where sims will say that message if you don't do favors for the sims in Henford on Bagley, that just sounds annoying.
