Yes, the Raspberry Pi will issue loads before the branch resolves. But usually a processor's pipeline won't be laid out in such a way that the AGU won't have time to pass an address to the load pipe before the branch resolves and squashes the load. The Cortex A8 was an interesting exception but it was pretty deeply pipelined compared to most in order cores.
