I agree that the "real Torgny" belongs to exactly one of those automata, 
but I don't know which one.  So I can not tell what will happen to the 
"real Torgny" in the future.  I can not do any prediction.

If we call the automata that the "real Torgny" belongs to, for automata 
X, then I can look at automata X from the outside, and I will then see 
that all that the "real Torgny" will do in the future is completely 
determined.  There is no indeterminacy in automata X.
