Do regular lighters not work at high altitude?

Here is what I would consider a regular Bic butane lighter.
However I have noticed that you can buy High Altitude lighters such as this one. Is that just marketing or would a regular lighter not work at high altitudes?

I think it does not matter which lighter you use if it's filled with butane. Lighter would not work if gas temperature close to boiling temperature. For butane it's -1C. For isobutane it's -11C and for propane it's -42C. Also propane has better evaporation properties. That's why gas stoves filled with 20% propane and 80% isobutane.
