I wonder why the CZ-2D is the only Chinese launch vehicle which de-orbits the second stage after the satellite has separated in orbit.

Do you mean the only Chinese launch vehicle? Falcon 9, Delta II and Atlas V have deorbited their second stages. Probably others as well. Perhaps the four vernier engines with their lower thrust and easier control enables the deorbit.

Just edited the original post so that it specifies Chinese, which was my intention.

Close in height to YG-12/YG-21 but slightly higher.

Does the similarity to Jilin-1 Optical mean the same bus was used, or just coincidence?

No this satellite is more advanced
