A question about hadoo io

Hi, all.
I am reading the SequenceFile code, and I have a question about hadoop compression io.
The code in org.apache.io.SequenceFile.BlockCompressWriter.writeBuffer:

deflateOut.flush();
deflateFilter.finish();

Why the flush() is called first? I think the compressor.finish() should be called before flush the output stream.
