The crown line on the side of the car is positioned lower than the CTS. That could just be the cladding.
The rub strip is placed lower than the CTS. That could be the cladding.
There is a white spot for a light on the lower corner of the rear bumper. There is a white spot for a side marker on the front fender. It is missing the corner front light of the CTS. That could all be cladding.
The top of the fender doesn't seem to meet the top of the mirror, as it does on the CTS. That could be the cladding.
Since there's no reason to disguise a current generation CTS, it's either an STS or the next generation CTS.

Anything is possible. But it's doubtful. Why would edmunds run an old photo?
In your very good morphing job. The mule is turned to the side quarter view, yet it's longer. Not just the tail end where the outside corner would appear longer, but also the inside corner of the greenhouse is longer. If it was the angle, it would be shorter.
That's just one of many differences I can see. I've listed some. But others are the angle of the rear end above the bumper. It is more upright on the CTS while the mule slants in at the top (as seen around the tail light section). The rear fender line is straight, not curved up like the CTS. The front fender line is lower than the CTS. There appears to be a turn indicator on the inside of the rear fender. The mule has a few more inches where the rear window starts to curve down than it does on the CTS. Again, the angle should lessen this effect.
Since the STS is supposed to share the CTS platform, then I would expect the wheel base to be similar. It's the styling cues that will distinguish it. I think there are enough signs here to point to this being the STS. And I think there's enough evidence here to show that the STS will be distinctly different from the CTS.
