Well, Brandon's discussion of it was that certain things(gods, moons, etc.) were all palindromes but regular people would try and name their children things that are *very* close to palindromes... without actually being one so as not to rise above themselves. For example, Shallan is almost a palindrome, only one letter off('sh' is a single letter in their language).
I'm betting on the first myself... but I'm also guessing this is a case of RAFO to get it confirmed... or someone ask Brandon at one of the Q&As.
Some of it is, but some is also strictly guessing on my part.
