it does not function as a lock. it functions as a gate, which you plainly
state below (even as you fumb duckly say is "not relevant").
The fact that it is only used to when the current runs north

It functions as a gate when the current runs south, as a lock when its
north. This seems to be too complex for your little mind to comprehend.
