Yep, I clearly understand how to limit orders works in ideal case. My question was about unusual case which can be handled ambiguously..
Maybe you might want to rephrase your query on what you want to understand. I have some experience in trading(well, not so much like 15 years, but I could help if I see something) and I could assist you to decipher what's going on. If you have screenshots or video, don't hesitate to share them, they can be helpful.
