Read the assumption
The Hand-to-Foot demo begins from a situation in which the selected action is legal. It does not choose which action a player should take. Say that assumption aloud before discussing the timing.
Try each path
Select a path, advance the illustration and read the explanation. Reset before comparing the other path. Keeping each example separate makes it easier to notice which step ended the turn and which step allowed further play.
Ask what is missing
A learner should be able to name the facts the diagram does not show: real cards, opening requirements, partnership conditions and any restrictions in another version. This prevents a useful simplification from becoming a false universal rule.
Keep a short note
Record the source and the distinction that resolved your question. The demo is a learning aid, not a referee for a disputed turn.
