Gzipped JS is generally much smaller than minified JS, but minified-then-gzipped JS is even more so. The minification (assuming gzip) doesn't make a much difference in this case only because the input file is not that large at all and compression algorithms have a natural bias for larger inputs. You can (rightly) claim it is bad to have a JS file large enough that the minification makes a difference after all, but you'd be moving a goalpost then.
