The tweet also shows three examples of what these tips might look like. The difference in the thickness of the tips will come into play although there could be other differences, including the material used, that will produce different styles depending on which of the three is employed on the accessory at a given time. The beauty of the system is, if the rumor is true, by using magnets, Apple will make it quick and easy to change tips on the Apple Pencil 3.
