Note that if OpenAI ends of changing their naming scheme to something else, I will count it if the model appears to be the one mentioned in this blog post: https://openai.com/index/openai-board-forms-safety-and-security-committee/

Additionally, it will only be resolved yes if 3.5 Opus sustains its position for the entire first month after both models are listed in the leaderboards, so if it passes GPT-5 temporarily due to noise it will not count.
