They are connected until (almost) all the exposed copper is removed. 
I would guess that some of the inside areas would not etch completely.
 He mentions a final etch with traditional etchants.  Clearly, a
little FeCl, CuCl or AP would go a very long way.

The need to have 2 etching set ups outweighs the benefits for me but
it is kind of cool.
