Thanks, but isn't this true for "normal" transactions as well? Then why the difference?

Only *blocks* are orphaned so typically a tx that has ended up in an orphaned block will just appear in the orphan's replacement block (or one very soon after it) but this is not the case with "coinbase" txs as they are tied to the one "specific" block that they were mined in (so effectively such txs are orphaned due to being unique to one specific block - so Bitcoin is being far more careful about the use of coinbase UTXOs).
