Honestly, no idea. I was told this place gets power from sins and virtues. Y'know, seven deadly sins, virtues as their opposites, all that crap. So I guess they chose memories that were powerful examples of those?

["Them" being the powers that be, the gods, or as Finnick would call them, the game-makers.]

Your memory, for instance, was voted to most represent chastity as a virtue. In other words, pure love. So, I guess you'll be sorted into chastity, maybe, or into a virtuous group, but I don't know what that means for you exactly.

[Not so terrible a judgement, to say this man loved his friend. That much was obvious. Finnick briefly wonders what his memory was voted as.]
