Is the effect of an Ability Capsule permanent?

Question

Does the ability get changed forever, or is it just temporary?

Answer 1

When used on a Pokémon, this item will change its ability to the other standard ability it can have. If a Pokémon only has one ability, it will not work. It will not change a Pokémon with its Hidden Ability or change a Pokémon to have its Hidden Ability. The effect lasts forever unless that Pokemon faints.

By 'unless that pokemon faints' do you mean it will lose the effects of the Ability Capsule if it faints in an online battle as well as in regular play, or just one of those two options?
