Did you read my comment? Currently, there is one Dragon and one Soyuz docked to the ISS. If Crew-9 had left earlier, before the Crew-10 Dragon had arrived, there would have been only the Soyuz left.
Do the Soyuz still touch down in a desert in a place like Kazakhstan or do they touch down on water nowadays? The desert solid ground touch downs seem so brutal.
Soyuz is always landing on ground (except in emergencies, and Soyuz 23 broke through a frozen lake). They do have Retro rockets that are fired shortly before contact and dampened Seats, but from the reports I heard, it's still a very rough landing.
