I'm pretty sure it does.

In warmer climates, fats go rancid faster. If you've ever tasted butter than has had that happen without sniffing it... yeah, not good eats. I'm betting that is why once you open the can, it is suggested to refridgerate the butter.

Heck, peanut butter and ketchup both suggest you fridge them after opening. Never put either one in the fridge in my entire life.
