>>27801414We don't know why Giratina has an "Altered Forme", don't make up bullshit without actual facts to back it up. Giratina was created in the "real world", and since its "Origin Forme" is called "Origin", it must also have been in that form in our world before it was banished.
The orb only exists to allow the players to change its form in the games. It doesn't play any role in-universe at all.
