The train in the waiting brakes is generally on a flat surface and brought in with drive wheels (because it’s also a transfer track) which is probably the fastest way to move it into the station and park it. It doesn’t really matter if a train that’s parked on the slope takes awhile to get to the waiting brake since it’ll be there long before that block is clear and since gravity is free and there are likely less moving parts this way it makes sense to me.
This would be my guess as well. The fewer unnecessary mechanical components, the better. Drive tires can get stuck, flat, or need to be repaired and can/do cause downtime.
