Yep, based on those headers it's the exact same thing discussed in the ZDNet and LinkedIn articles.

ETA: Just tried it myself, through my own mail server, and the headers are pretty much the same: the IPs are different, of course, and I didn't bother including extra forged Received: headers and such). This works beautifully -- message is in my Inbox (flagged as "Important according to Google magic.") and shows up under "Sent" as well.
After opening up "Show Original" in a new tab and then returning to the message, there's now a small banner (with a yellow background) at the top that reads:
> This may be a spoofed message. Gmail couldn't verify that it was actually sent from your account. Learn more.
