Sand has the habit of stopping skids quite abruptly ...
If you are used to do autos with a bit of forward motion (on gras/asphalt) you might not aim for 0/0 in the real case
Photos show some longer skid marks - so my guess would be - witch decaying rotor rpm the helicopter stopping hard and some input in the cyclic brought that outcome.
Still, every landing you can walk away from is considered a good landing - the ones, where you can use the aircraft again, are very good landings ;-)
