How to close Camry non interference engine valves when opened?

Thanks for looking into my question. As the timing disrupt (timing belt snap/break) on NON interference engine, it stops (rotation stops) with few valves open. It protects engine/valve damage. I am asking on this condition, how does a mechanic able to close such opened valves? .

By simply turning the camshafts.... Valves are spring loaded and will close as camshaft is rotated to the correct timing position... No other action is required.

Thanks for your reply. I like to have your insight on following engines animation. http://www.samarins.com/images/engine_animation6b.gif https://www.youtube.com/watch?feature=player_embedded&v=O9tfIfwlmz8 Are the above animations for non interference or interference engine? I find 5S-FE engine as DOHC kind. Do all DOHC engines non interference? Does any of the above animation resembles 5S-FE engine? Thanks for guidance.
