As it is, we're only speculating that the Kingdom symbols include relics. Vale's is still a bit odd. The only thing that speaks to "choice" is the duality of it and a relic that is actually two separate things is confusing. Certainly seems to me that on some level each symbol evokes the relic being housed in that Kingdom, though whether the relic itself is depicted is another matter.
