A pipe isn't seekable, but the redirection probably is (can't test right now, but I learned earlier this year that redirected input is seekable, in connection with the pipe rewind problem). So it would appear that the wrong number is written on the first pass, then corrected (or not) after the remainder of the file has been written.
