Points don’t go to contracts but membership and it’s all based on UY of the points going.
They also retain all their same rules, they just sit in a different spot. Think of them as shelves.
Your Aug UY is the top shelf and Dec UY is the bottom.
When you move Dec 2026 UY points to the Aug Iy shelf,
DVc creates a temporary contract to hold them. They are still Dec 2026 UY points
Because you are transferring between your own memberships, it doesn’t count as your only one. You can do multiple.
But, if it did, that would count as your one and only for the 2026 UY for both memberships.
