Actually one of the few political pressures Putin has had to deal with internally has been preventing conscripts from fighting outside of Russian territory, which has included not sending them into the supposedly-annexed oblasts in the east. They've had to make do with massive signing bonuses, prison recruitment, stop loss, and PMCs to make up the manpower shortage. Definitely some high-pressure tactics in use, but no actual use of legal force. Unless this video was taken on the Kursk front then any Russian soldiers who this was targeting had signed contracts that they could have chosen not to.
