blunder in discord pointed out what is going on;

The display of Experience is bugged, it "adds" the per minion XP for that fight, but doesn't correct for the RoE redistribution

Good thing ya'll figured this out, because I was gonna be real confused when I saw the same thing on my next run! I'll be using a named RoE with a 4 minion team!
