As I said very clearly in my previous post: Views do not have their own submit options and they do not have their own data connections. Nothing is "cascading" because the submit options and data connections belong to the form template, not the views.
However, you can add as many different data connections as you want and use them at different times so that is not a problem. And to repeat what I just said, my suggestion was to not use the submit options, and create buttons with rules that carry out the submit using the rules.
