Actually to be honest, Circles wouldn't always preventing them from learning that they were both connected to you.
After messing up badly in the nymwars, forcibly joining together YouTube accounts with Gmail accounts they actually made a heavyweight but working solution:
It was given the name Pages which was more or less meaningless IMO (in this context).
What it felt like at the time however was a powerful solution for switching between pseudonyms connected to your account.
That said: Given a large reason for why Google+ is shutting down was that they had a couple of huge data leaks maybe we should all be glad kt wasn't too widely used :-]
If something is public (and often even if it isn't), it's public. I never viewed Circles so much about hiding information from other Circles. Rather, it was about acknowledging that my friends from school and other non-professional, well, circles mostly aren't interested in reading about my latest tech article. And at least some people who follow me professionally probably aren't interested in whether I think some movie is good or not.
I really tried to be on team Google+ for a while but it was too little too late.

That's the reason it's already planned shutdown was accelerated, but the leaks occurred after it was essentially abandoned to palliative care.
Had it been sufficiently used, and therefore actively maintained, they may not have occurred.
