Why would my neighbour swap license plates?

I noticed my neighbour the other day drive in to our communal car park with a personalised license plate and then after parking he removed it to reveal another one beneath. He did the same at the front, looking online the 1st plate brings up a black Land Rover and the 2nd plate brings up a blue Land Rover. He has about 5 cars and frequently changes them and seems to mix & match plates. Could he be doing something dodgy or is it all perfectly legal?
