Duplicating a brain is not enough, the intelligence has NOT forked
until there is something different about them, such as one
remembering seeing a red ball and the other remember seeing a green
ball, only then do they fork. It was the decision made by somebody
or something outside the simulation to make sure all 256 saw a
difference sequence of colored balls that created 256 distinct
minds. And to a simulated physicist a decision made outside the
simulation would be indistinguishable from being random, that is to
say the simulated laws of physics could not be used to figure out
what that decision would be.

A occurred first or test B occurred first.
Both A and B are identical in that the intelligence doesn't know
what it is going to see next; but increasingly convoluted thought
experiments are not needed to demonstrate that everyday fact. The
only difference is that in A lots of copies are made of the
intelligence and in B they are not; but as the intelligence would
have no way of knowing if a copy had been made of itself or not nor
would it have any way of knowing if it was the original or the copy,
subjectively it doesn't matter if A or B is true.
So yes, subjectively the intelligence would have no way of knowing
if A was true or B, or to put it another way subjectively it would
make no difference.

Yes, the conclusion is the same, and that is the not very profound
conclusion that you never know what you're going to see next, and
Bruno's grand discovery of First Person Indeterminacy is just
regular old dull as dishwater indeterminacy first discovered by Og
the caveman. After the big buildup it's a bit of a letdown actually.
If step 3 is that easy, then you can surely proceed to step 4.
So what about step 4?
