That step of the journey is actually completed by dragging a purge thrall to the wheel and interacting with the wheel to place them inside.
It’s not triggered when the thrall is converted or when placed in the bench, only when put in the wheel from a rope.
So the trick here is that the thrall you knocked out in Step 2 would actually complete this step, but you first need to complete the purge and only THEN drag the thrall to the wheel.
Ofc you can complete this step during the next purge
