Does it matter if a joint chain is in hierarchy?

I'm basically wondering if it matter if a joint chain is in hierarchy or not? I'm talking about the hierarchy of the imported fox joints not the actual configurableJoint if that makes sense :P

Does it affects the behavior of the joints when rigid body and configurableJoint connects them? And bonus question, what is the proper order for the joint component to be attached? Do I connect the spineJoint to the configurableJoint on the hipJoint or vice verse? I know this is probably obvious but if tried both and they both are a bit "buggy" but in different ways

Thanks :)
