There should be a hook and tie down similar to the front on the passenger side rear near the trailer wire hookup. Only on that side.
The loop is shaped differently than the front ones, angled down, likely to help a recovery rope/strap clear the bumper skin. As a result, in terms of pure strength I'd say this single loop isn't as strong as the front ones.. but we have no real idea how much force even those can withstand, nor truly how much force is involved in different recovery scenarios.
Either way, even if it is strong enough, it isn't centered. Given the availability and low cost of trailer-hitch recovery adapters, I'd go with one of those, personally.
I even sought out one that has the hitch pin hole drilled both the usual horizontal as well as vertically so it can be turned sideways if needed for a side pull/anchor and still keep the shackle in the correct loading orientation.
Now personally if I were doing a side anchor, I'd consider running my lifting sling through a wheel and avoid putting the forces on my panhard rod.. but maybe we shouldn't open the recovery techniques can of worms here.
