Can I nominate the same assets for both One-Year and Perpetual Free Collection?

Hi everyone, I need some clarification about Adobe Stock’s Free Collection.
I’ve heard that:
-
If I select only the One-Year Free Period → Adobe may select some assets.
-
If I select only the Perpetual Free Period → Adobe may not select any assets.
-
If I select both One-Year and Perpetual → Adobe may not select any assets either.
Is this actually true, or is it just a rumour?
What would be the safest option to select? I’d really appreciate advice from experienced Contributors or Adobe staff. Thanks!
