The output of the AND gate will remain 0 after the lower input to the flip-flop returns to 0.

The 1 on the lower input is negated to 0 by the NOT gate, causing the output of the AND gate to become 0. Thus both inputs to the OR gate are 0 (remember that the upper input to the flip-flop is held at 0) So, the output of the OR gate becomes 0. This means that the output of the AND gate will remain 0 after the lower input to the flip-flop returns to 0.
