    Don't you mean (2^N)x(2^N).


Probably. Both Alice and Bob split into 2^N copies for binary results. So each of the 2^N Alice's splits into 2^N further copies, one for each copy of Bob.

Why would Alice split again for each copy of Bob.  There's no QM involved.  Each Alice and each Bob has seen N events and has recorded them as a binary number of N bits in their notebook.  They are quasi-classical observers and they're going to meet in the future.  If there are not (2^N)x(2^N) meetings there must be some quantum magic that it is eliminating or otherwise weighting them.

That seems to give (2^N)*(2^N) pairings. That is still a lot of redundant copies when only one copy of Bob meets each copy of Alice in the actual experiment.
