Who's the Creator?

Something really creating confusion for me since the begining... Who is the creator and who is the exchanger? The Redemption Manual seems to show me/the secured party as the creator and another party as the exchanger... I think thats because the exchanger won't always be the same person but it's confusing and I'm not sure, it seems weird to just sign my name twice in a row on two lines right next to each other but as far as I can tell, for the SPC trust, I am also the exchanger and that's what I'm supposed to do. Furthermore, if my government/parents created the trust at my birth, wouldn't they be the creator(s) instead of me?
