Those Boeing test flights are for certification at extreme crosswinds, with no passengers on board to complain.
I think it's instructive to see what the autopilot does, as "George" has no opinion, only programming.
On the 747-400 the autopilot uses crab angle, but at 500 feet AGL inserts up to 5 deg sideslip (i.e. wing down) to reduce it as much as possible without risking a pod strike. It lands wing down, with some crab depending on how strong the wind is. So with winds where crab angle would be less than 5 degrees, the autopilot technique at touchdown is exclusively "wing down".
757 and 767 autopilots use similar technique (crab then wing down).
The 747-200 in contrast will crab in until just 2 feet Radio Altitude at which point Kick Off Drift mode activates to start driving the rudder to line up with the runway. Clearly without a proper yaw channel they didn't want to take any chances.
