Review comment:
Can we abstract the common logic `config.isKeepSortInSubQuery() ||
bb.top` into a method there ?
```java
/**
* Returns whether we should keep the sort for the subsequent query
conversion.
*
* @param topQuery Whether the query is in the top level.
*/
boolean keepSortInSubQuery(boolean topQuery) {
return config.isKeepSortInSubQuery() || topQuery;
}
```
