Uh, no?  The difference is that in the top staff, there are isolated
note events starting an implicit Voice, while in the bottom staff, there
is no isolated event but rather a sequential music expression that gets
its _own_ \new Voice ending at the closing brace.  If you had written
wrote

{ { c4\p c c\f c } | << \Ms \Ds >> }

above, you'd have gotten the same.  Note that | is just a barcheck and
not an event starting (or maintaining) a new voice.  So \Ms starts its
own, new voice, and then \Ds does as well.

Of course, if you wrote \new Voice everywhere where you write \new Staff
now, LilyPond would have put everything into the same Voice either way.
