Sorry, I made assumptions that people knew what gzip was. EDIT: That wasn't meant to be condescending, I apologise.
To clarify the original comment: I think it's rather pointless to gzip a PNG file, since PNG files use deflate compression, the same method gzip uses, and hence it has very little real benefit, if any.
Your look of disapproval seems to have overlooked why he said he was using it. He's clearly aware of your point, and even mentioned the uselessness: "Up to 1% savings" while explaining why: Google Page Speed is stupid.

Yes, I was pointing out the stupidity of that further because you're compressing something twice.
