I do agree that this last sentence (the one you quoted) is very unfortunate and doesn't match the wit of the rest. A better closing remark might have been something on the lines of, “I never claimed to have performed any compression. I only claimed to have met the terms of the challenge. I asked if I can send multiple files and the response was ‘sure’. I provided the files; they meet the total file size criterion; and the script correctly reconstructs the original files.”
