Strange behavior with chaining and indented objects as function arguments

[dhr]

This

house = ->
  foo 'bar'
    .chain
      key: val
    .someMore()
  im at, home

compiles as

var house;

house = function() {
  foo('bar').chain({
    key: val
  }).someMore();
  return im(at, home);
};

However, this

foo 'bar'
  .chain
    key: val
  .someMore()

house = ->
  foo 'bar'
    .chain
      key: val
    .someMore()
  iWant toGo, backHome

compiles as

var house;

foo('bar').chain({
  key: val
}).someMore();

house = function() {
  return foo('bar').chain({
    key: val
  }).someMore();
};

iWant(toGo, backHome);

Why? Removing either .someMore() call puts the final line back inside the function.
