In Soul Mates, both Lois and Clark were reincarnated (transmigrated?) several times (but oddly , always into bodies which were visual replicates of the same model -- which has interesting sci-fi implications, but I'm wonder-wandering off topic here --- Also, in Soul Mates, Clark was not always "super"- he dies in that medieval duel , for example.
I have chosen to interpret the visual replication as an effect of how Lois & Clark got there - since they were 'awakened' soul-stuff in other bodies, they were seeing representations of the 'souls' of their group and the easiest way to represent that was by showing familiar faces.
Now, back to our discussion.
