Maybe I picked up on the double grooves from the linked-to video?
Yours are not double.
There's no choice when it comes to the seal ID, you'll use seals for a 11/32" stem and the wear will be compensated for by the seal having a smaller ID than the valve stem. Go ahead and use the second set, no need to buy two sets.
