It kind of does because individuals who have a higher caloric burn likely do so from increased activity, and increased activity does increase electrolyte demands.
There really should be no daily recommended sodium intakes for all people as a general rule. That’s very individual.
In all honesty you probably have no reason to track your sodium intake.
An over simple view:
The 2g limit is (supposed to be) based on how much the average kidneys can filter, the average water intake, and losses via sweat.
The recommendation is based on your body’s health, not how much salt tastes good per calories served, which would mean more salt for more calories.
(The recommendation amount is hotly debated, ask your doctor how much they recommend for you)
