Because the machine is byte addressable as opposed to bit addressable; therefore adding 4 advances the pointer by 32 bits. The address bus wants the location in bytes. There is no way to address individual bits. It's entire possible that it's actually incrementing the PC by 1 and the low two bits don't even exist in the register.
