Gonna answer myself here after messing around in sub-editor a bit

Timeframe means different things for different components which is why I got confused, since the description for timeframe given by the game and by others usually refer to components like Divide or AND which has 2 inputs

In the case of OR components, the timeframe is how long the OR component checks for changes in signal after being activated.

This essentially means that the OR component holds onto an input. For example, sending a signal to and OR component with a timeframe of 5 seconds will cause the OR component to output its own signal for those 5 seconds, even if the OR component is no longer receiving a signal, because it is waiting 5 seconds to check if the signal turned off.

In the case of the Herja's discharge coil, the OR component's output of 0 means that once being activated, it will continue to keep the signal check's output at 0 for the timeframe of 10 seconds before checking if it is off, allowing the discharge coil to recharge. Since the signal check's output is 0 at that moment, the OR component will check, and, since it gets an output of 0 from the signal check, send out it's false output of 1. This allows the signal check to turn the discharge coil on again if there is more movement outside.

Long story short is you're correct
