I'm having a tough time understanding what exactly WTXID is and what it means when WTXID and TXID are the same (and vica versa).
What I understand is that WTXID includes the witness data. Since non-segwit transactions do not have the witness segregated, their WTXID should be the same as the TXID. Is that correct?

The wtxid and txid are the same if and only if the transaction does not contain any segwit inputs. The wtxid is the hash of the entire transaction including all segwit data (i.e. the marker and flag bytes and the witness fields themselves). The txid is the hash of the non-segwit parts of the transaction. Because a transaction that does not have any segwit inputs does not have any segwit data at all, both the wtxid and txid hash the same data, so they are the same.
