Depends what you mean by "real state". It doesn't necessarily
correspond to a flipflop in the hardware implementation, but
it's definitely state in our implementation. (Conversely,
the hardware implementation has state which our s/w one does
not, most notably we don't use the command and data state
machine approach the hardware has.)

No.
