You bring all of the charges so that the jury can convict in one of multiple ways. Also it is possible that both are correct, but he would still only be found guilty of one.
e.g. A law says murder = A + B, or C + D If the defendant did A,B,C, and D to the same person he is guilty of one murder, but the jury only needs to find A + B or C + D. If the prosecution only accused him of doing A + B and the jury believes C + D, you get a not guilty verdict, thus you throw it all in there.
