There is nothing anywhere to say that the airline won’t change the flight number or reuse the same flight number to connect different destinations.
Case in point: United flight 237 contains 2 different segments flown by 2 different aircraft today so in essence you can look at it as 2 different flights.
On occasion airlines change flight numbers for the same destinations due to various conditions most notable one is an accident for example Moscow – Hong Kong is now flight SU212 but it didn’t used to be and so on.
Just about the only thing that you can expect is that flight number for a regularly scheduled flight will change sufficiently enough in advance of bookings/reservations so that airline doesn’t have to notify clients of the change midstream.
