So I looked closer at the file and I'd say the behavior is actually correct, even though it may seem counter intuitive. I realize it "worked" in previous builds, but it "worked" because in previous builds the logic was a bit broken.
What you actually want to do is start off with your first particle...then spawn *two* particles from it, spreading one of them and then resampling them with the sibling resample method. That way all particles in the chain are siblings. Finally, bind them as siblings and don't bind to parent.
I've attached a scene file with the modification showing you how this is done.
