No I didn't. I asked the (IMO perfectly reasonable) question as to how the device monitored "the size of the load" whilst the (main) circuit was open.You asked how the device could monitor how much current was flowing after it had opened the circuit so that no current was flowing.
There's no need to apologise, but see above.I'm sorry you regard it as silly and unhelpful to point out that the load would be zero.
Kind Regards, John
