> The conclusion was that you don't get interference regardless of what you do at the other end, because the paths are potentially distinguishable.

That's not quite true. The conclusion was that there actually *is* interference at the other end, but there are *two* interference patterns that cancel each other out and make it *appear* that there is no interference. You can *apparently* produce interference by bringing (classical) information back form one end of the experiment to the other, but you aren't *really* creating it, you are just "filtering out" interference that was already there.
