This is known as economy and it is highly appreciated in compositions. You combine more options in less material. When your composition appears to be finished, it is always a good idea to invest some time in making the position more economical.

For instance it's better to have a bishop than a queen on the same square - but not when it adds promoted pieces or loses interesting variations!
