I don't understand how single point fueling will do a better job of
preventing using the wrong fuel.

Going to a single point system requires the use of a special pressure
feed nozzle. The nozzle locks onto a mating recepticle on the a/c.
With this system, all tanks are filled through the single connection.
The system is a bit of overkill ( to put it mildly ) for small a/c,
but we are going to start seeing it soon with the practicality of the
personal jet ever closer.
