Duh. Yes. I'm so accustomed to working with % solutions (weight by volume) I forgot nutrition labels give %DV.
Comparing, my costco mexican coke = 85mg sodium in 355mL, my gas station coke = 75mg in 591mL.

The percentage DV isn't telling you how much of the food is sodium, it's some reference to some "ideal" diet and food intake.
If the percentage of the drink was the same, the larger serving would have a higher amount in milligrams. But despite being almost 240mL more it has fewer total milligrams of sodium! .13mg/mL (US), the other is .24mg/mL(MX).
Is .24 == .13? Which is a bigger number?
So repeat after me, the %DV is meaningless. It's not telling you what you think it is.
