VoG - Gorgons Area changing/reacting differently

I've been testing new theories mostly based on speed between areas. I beat the Templar, he teleported, and the entire group went through the Templar door. (Not the secret path) I rushed ahead, fast; High agility and mida-multi tool. I made it to the Gorgons, I tried rushing to the floating platforms ahead of everyone, hoping speed was required for the secret chest. But when I got in the Gorgons area it was different, the cave in the wall leading to the floating platforms was gone. It was just a wall. Which meant, the Gorgons area I was in was a Different* one. Either it doesn't open until the whole team is present or i did something different. This means, that OTHER areas of the Gorgons maze could have been different, new openings and caves ETC.. I rushed to try and explore the whole place but as soon as I got 20 feet from the closed entrance some asshole jumped down and got spotted. The Gorgons area reset back to normal after that. I lost my opportunity but I hope other people can try this to see what they can find. I think I found a wall that could open for a chest but no time to test. It was on hard mode. We started at oracles. Nothing specific happened else that I can note...
