@Embellem: Didn't MK sort-of explain that about Semblances in a panel? That people can have "basically" the same Semblance but with aesthetic differences.

Far from the best explanation, but considering we're getting an Info Dump book incoming, not much of a problem. And much better than grinding the plot to a halt for half an episode to explain something that could've been explained in 2 minutes long ago (say, in WoR).
