Not necessarily.  It is quite possible to be able to read a state from
neurons - measuring the electrical and chemical state - without being
able to recreate that state.

It's like the difference between the skill of literacy, and having the
knowledge and ability to manufacture pens or pencils - or knowing that
the letters are created by depositing pigment on surfaces.  (For
instance and slightly analogous, one may have learned to read from
pictures.  While one might know how pictures are taken, not having
personally inspected the things that pictures are taken from, one has
not had a way to reverse engineer the process of creating letters.)
