Sure, no problem Matt. If you look at the very next paragraph that follows the photo of the parting tool you'll find this:

"Please note that I performed the above operation so that I could photograph the process. I didn’t bother to adjust the grinding table to a better angle so the parting tool has a MUCH more acute angle than the desirable configuration. A tool with this much front rake will quickly break down with use. I’ll re-sharpen at the correct angle before using it, be assured !"
