is there a way that once OUT drooped back to LOW, OUT1 will also drop to LOW ?
currently it strays at HIGH until I press on the ON once more.

No, that's the way the bistable circuit works.
Why do you want OUT1 to go back low? Its going low is what triggers the output to turn ON.

I was referring to D1 in the post #7 circuit, not the post #6 circuit.

Okay.
Since he was replying to my post #11, I assumed he was asking about the post #6 circuit.
