I used to work in ISS mission control, this is not an emergency return but an early return
Also coming down on the Soyuz is pretty routine and only takes a few hours- I’d say it was overall a far less risky situation than being in Antarctic on a deep ocean vessel with appendicitis etc
We have dozens and (hundreds behind them) of men and women monitoring those folks from a global network of control centers 24 hrs a day- The station is mostly commanded from the ground and plans and procedures exist for everything
- if anything its all over orchestrated and over-planned in my opinion, owing to national politics, corporate contracts and international bureaucracy
Is it risky- yes obviously-but I’d argue its less risky then being out at the south pole in winter

or on the way to Mars.
Then why did you mention Soyuz when Dragon is coming down early?
