Simple. Below design means the engine, transmission and rotor system is good enough for High Altitude, below design is mainly for Infrared Signature Suppression, at the cost of less power efficient.Why's that even more interesting?
Yeah, I get that. What I asked was why @Deino thinks it's more interesting that these are in the Xinjiang Brigade.Simple.

The combat areas near the border with India Army are 4000m-6000m, half oxygen, lack of road, cold, windy, snowy. Solders have to carry as much as possible, including tent, food, weapons, ammunitions, communication equipment, bulletproof vest, while climbing the damn high mountains.
The closer you can send your troops and supply to front line the better, it's a matter of life and death.
Infrared Signature Suppression is more important than armor. No matter what armor you have, a Stinger missile can send the millions dollars helicopter to hell.

US Blackhawks and Seahawks can't utilize hellfires, only carrying gun pods at most. Whereas China WZ20 copy could carry AGM. The article here said prototype belonging to PLAN. If the army wanted WZ-20 to carry AGM is more relevant especially for Tibet border LAC Ladakh, Sikkim providing close air support should there be battle.
