Review Comment:
I think it's because we sometimes concat multiple batches and sort them
in-place, while emitting this larger batch as-is.

The test case where this in-place sorting happens is `cargo test --package
datafusion --test core_integration --
sql::runtime_config::test_memory_limit_with_spill --exact --show-output`
