It should work fine. He will probably have to lower "bus on" time in both cards, since they both will steal DRAM refresh cycles during DMA. He will also need to make sure that they don't share any settings, and that his non-default setting on one card do not conflict with the other. Finally, he will have to disable the BIOS on one card -- probably the B. The ^A stuff might screw the B card badly...
