No, that link is for 2 mirrors.

What Prof. Hicks made is a single curved mirror. That is new. That is why his results got published and he was awarded a patent for it.

If you had bothered to read the linked article, you'd already understand the distinction.

The curved mirror exhibits distortion at the edges, which doesn't seem to be a problem with the two-mirror approach.

Also the curved mirror doesn't present the image at full size, it appears smaller.

I agree that it is a neat implementation. I just meant that the idea of a non-reversing mirror is not new.
