'react/jsx-wrap-multilines' behaves strange

The [rule](https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/jsx-wrap-multilines.md) tells me that this is good:
```
var hello = (
    <div>
      <p>Hello</p>
    </div>
)
```

but this is also accepted:
```
var hello = (<div>
  <p>Hello</p>
</div>)
```

```
'react/jsx-wrap-multilines': 'error'
```

Did I miss something?
