The fuel from the previous fill up stays in the hose. So if you are filling up with 91 and the last person bought 87, you'll have at least the entire hose's worth of 87 gas, if not a tad more.
Eons ago, Shell used to have a separate nozzle for V-Power, but I don't think I have seen separate setup like that for a very, very long time. I think Chevron is the only one that does it now.
