It's not the same, YG-41 was a massive satellite that used a special LM-5 variant with extra long fairing. Making that specific vehicle the tallest Chinese rocket built to date.

The inclined MEO regime for that satellite is pretty unique. Maybe they're building a multi-layered architecture from LEO, MEO to GEO for persistent coverage in a way that doesn't rely on having thousands of LEO sats. Data and telemetry from higher orbit sats can be used to 'cue' the YG sats in LEO.

About YG-41 itself, there is (academic) interest in a 1m resolution capability from GEO but this requires novel optical technologies simply due to the physics
