Using shifts to clear bits has it's advantages. Mainly because to and something you need to load a value into a register and then and between two registers. Using bitshifts to cut off bits you don't care about is often simpler because it requires only one register.

If I'm not mistaken though and directly edits the contents of one register, so it only requires one register as well.
