Are there any same pool_id for pools on different network?

I am wondering if there is a pool_id on Pre-prod testnet that appears on Preview testnet or Mainnet. As far as I know there are some pool_ids that appear on both Preview testnet and Mainnet.
Can anyone please explain this to me. Thank you very much!

You can use the same pool keys to create a pool on a different cardano chain.
Could also use the same for mainnet, but security wise it is best to keep them different.
By doing this we give the same pool_id’s.
