On second thoughts, I'm guessing that what this ACTUALLY does is make sure that the petrol engine doesn't waste fuel recharging the battery unnecessarily at the end of the trip when it's going to get plugged in.
I like that idea - it means if you are doing less than 22 miles you can run it as a plug in hybrid and not use fuel. I used to have an old high performance sports and the fuel use for going down the shops etc was annoying.
