You do not have to. The calculation of the possible next
states comes from the current state. You still use the slow
input signals just to select one of the computed states at the
very end (like in your aproach). The only difference is
that "my aproach" might save us some of the duplication by
eliminating more of the "paths" that we do not need to follow.
