If the pick path drops, what would happen to the stick path? (ERS)

Explanation:
In this kind of signaling logic, the stick path acts as a holding or latch that keeps the control state active after the initial action has been triggered. When the pick path energizes the circuit to operate, it also sets the latch that powers the stick path. Once the latch is set, removing the input from the pick path doesn’t immediately disable the stick path—the stored energy in the latch keeps the stick path up until there is a deliberate reset or release signal. That’s why, if the pick path drops, the stick path would stay up. The other outcomes would require a separate action (like a reset) or a different circuit design, but with a proper latch, the stick remains energized even if the initiating input falls away.
