"\n" composes a balanced expression, obviously doublequotes are a matching pair of delimiters:

  Balanced expressions typically include individual symbols, numbers, and string constants, as well as pieces of code enclosed in a matching pair of delimiters.

also seen from usage, that command should never fail, unless beginning or end of buffers are reached.

backward-sexp can't deal with it, but that's just a bug.
