The B777 is limited to a max crosswind component of 25 knots when using Autoland so it is most likely that it was a manual landing in the photo above.
The B777 has a "max demonstrated crosswind component" of 38 knots. Some companies will round this up to 40 knots for a company limit.
The "max demonstrated crosswind component" is not a limit. It just means the aircraft can land with that wind speed, in a crabbed configuration, without damage to the aircraft or landing gear.
Crosswind landings for certification are done in a crabbed configuration. Boeing has demonstrated landings for the B777 with a 38 knot crosswind, so that becomes the Demonstrated Crosswind Component.
If Boeing had tested with winds greater than 38 knots, AND it resulted in damage, then the B777 would have a 38 knot Crosswind LIMIT.
Of course there was no damage at 38 knots and there is nothing preventing pilots from landing with crosswind components greater than 38 knots.
Since Boeing has not tested or demonstrated crabbed landings ABOVE 38 knots, we don’t know what the actual limit is when damage may occur due to side loading.
So when landing with a crosswind greater than 38 knots, it would be prudent to use a technique that would involve a slip and removal of any crab at touchdown so that excessive side loading is avoided.
