you actually can, that's why it's interesting. i have a save where i'm not on Lisa's path, having rejected her at every turn, but i was able to both kiss Jade and enter Jade's path in this update and have the 3some scene at the end, with Lisa blowing the MC after they never even kissed before in my playthrough.Probably because you can't be on the jade_path, without also being on the lisa_path. So checking both would be unnecessary.
