If you use global binding then this is what happens. In fact, the rationale for global binding is this only. If you just change the binding type, you can get different values. I fail to understand the real use case here. Do you want different values despite using the global binding or you want just ...

The mast page fields for every page are different and can be assigned different values.

I am not sure why do you want different names. Even same name fields can pretty much solve what you want. In fact in XFA world if you use 2 fields of same name they will be assigned separate SOM expression. 

Anothe solution could be not to use global data binding and instead switch to 'Use name' binding. Global binding is designed to show same value in ssame name fields.
