And yet when we see him first talk to Nozarshi, Yachiru is up with Isane, oblivious to everything and using her own Shikai in battle. She did not do anything until she saw his release, which is meant to be her? How did she get released or achieved without her even knowing it or realising it?

While personally I agree shes linked to it, her actions and thoughts and make up throughout the story just do not make sense. Perhaps she's a manifestation of Nozarashi while slightly separate because he refused to try to talk to his spirit, just killed lots and that how she was born in blood or her earliest memories are blood and didn't react to Zaraki.

There is not enough explanation of it for us to say outright. We know that multiple spirits can exist inside people. But as it stands the article has all the information the Manga gave us, everything else is speculation at this point.
