Neither. It simply means that the two music expressions ("c1" and the "<< ...

The cause here is once again our beloved implicit context creation... In the
above case, no voice or staff has yet been created, the << does also not
create one, so when lilypond sees the c1, it creates a voice+staff. When it
then processes the s4\<, it does the same, because it is apparently not in the
same voice (which was only created for the c1.
Wrap \new Voice aroud the <<....>> to explicitly create the voice or staff and
it will work:
\new Voice { << c1 { s4\< s2\! s4 } >> }
Cheers,
Reinhold
