I thought you had gravely misunderstood the article because the author leads with discovering the lossless compression support of WebP and even compares it to advanced lossless compression tools like PNGOUT so I thought he wasn't comparing apples and oranges.

But no. He DOES in fact compare lossy to lossless in the end, arguing the difference is hardly perceptible anyway. Which it is! I could see the loss of chroma when opening them on my desktop here. I don't understand. JPEG also compresses a photo better than PNG? What's the point?

This is just confusing. Sure, for personal use, do whatever you like, but in a comparison...

It would be interesting to see WebP Lossless vs PNGOUT. And/or WebP vs Mozjpeg. :)
