Hello!

I'm really confused about this paper's mark scheme. Someone help me please? :)

What I dont understand is, how come the textbook says hydrolysis of ATP is for myosin head to detach from the exposed sites on actin, whereas for mark scheme, it says the hydrolysis of ATP allows myosin to tilt and binds. Which one should I follow?
