Recording events straight to csv

While digging through the documentation, examples, and source code, I found a rather poorly documented feature of the python HAL API, and I am wondering if it works the way I think it does. I have tried a few examples and had some promising results, but I want to know if this is a supported feature of the API and whether there are any caveats I should be aware of. Below I have posted some example code.

# assume that camera discovery is already done and we have a device
cd_decoder = device.get_i_event_cd_decoder()
stream_decoder = device.get_i_events_stream_decoder()
stream = device.get_i_events_stream()

cd_decoder.add_event_buffer_callback(lambda buffer: save_csv(buffer, 'test.csv'))
streaming = True
camera.start_stream()
Timer(5, lambda streaming=streaming: streaming=False).start() # Stop streaming after 5 seconds
while streaming:
    data = stream.get_latest_raw_data()
    if data is not None:
        stream_decoder.decode(data)
    sleep(0.1)

The code makes use of the event_stream_decoder and cd_decoder to write data directly to a csv file rather than recording to a raw file and then converting it. Would this result in (more or less) the same events as if I recorded a raw file and converted it?
