TFA for me gives the same link for the "Compressed using pngquant - 59,449 bytes" as the first image: "test1.png" and it's about 191 KiB.

I think it's a copy/paste error for replacing the link with test3.png instead of test1.png gives the correct file.

For the curious ones here are the result of compressing both losslessly with WEBP:

    195558 test1.png
    102750 test1.webp

     59449 test3.png
     38304 test3.webp

P.S: that picture is called a "test card": https://en.wikipedia.org/wiki/Test_card
