I don't know who said this but its wrong.
Nothing happens to coins on a paper wallet. You probably read the sentence wrong. He probably said you *could* lose something that is on paper.
Meaning, its possible to misplace it. The coins don't sometimes "get lost" from paper wallets.
In fact, the coins aren't really there. They aren't anywhere. The blockchain is an accounting ledger, documenting where the wealth is.
The wealth is virtual. The paper wallet just houses the private key. And its the private key that unlocks your ability to move the coins from their location documented in the ledger.
There are no coins on your paper wallet, and they can't be lost.
