Are you sure? The law says the pilot must pay at least, not exactly his share and that there can not be more than 4 people in the aircraft when cost sharing is happening. This is true in both cases (the pilot has paid half and there are three people)
So both of your two examples are legal as intended. Peter's is a somewhat complex set of facts and I have some sympathy with the inability to legislate specifically for every variation of facts.
