Resolution Note:
This issue is expected in the sample scene since the playable graph is connected during the 'LateUpdate' which has run after the animation update. Changing the playable graph topology resets the character to bind pose but since this is done after the animation update, the new playable graph doesn't have a chance to run.
I managed to make the scene work by changing LateUpdate to Update.
