My manual says to fill to the metal ring inside the neck. To do this pump nozzle has to be nearly out of tank. Most tanks have a high spot higher than fill point to trap an air pocket. Heat expanding the pocket of air is typically what pushed gas out of tank.
I had a Piaggio MP3 with vent in neck of tank. If filled higher than vent an air pocket would expand pushing gas to the charcoal filter and plugging it. With filter plugged tank could have vacuumn or be pressurized. A friend had his gas cap blow past his face when opening at pump. Like many I removed the filter. If tank filled too full on hot day gas would be pouring out vent line before I could pay for gas. At least it wasn’t plugging filter.
