I'm not sure about this. This means only two lines can be patched, which would be very limiting. The patents suggest that updates can patch any 64 lines out of the 3072 in the microcode array. This is probably not the exact number in K8 cores, but it may be close. Probably the addresses to patch are within the data area itself.
