Attribute precedence

FIMMA has  value for firstName attribute. I have 2 other MA's flowing values to firstname in metaverse. MA1 with higheset precedence and MA2 with 2nd and FIMMA, the least. If both the MA1 and MA2 are disconnected, wouldn't the firstname be going back to what FIM had previously?

In my testing, I could see the last connected CS value is retained. Please help.

Thanks!
