The split is intentional, and allows for trustless watching of revoked transactions, which is often outsourced with the help of watchtowers.

From Bolt3

> Splitting the `local_delayedpubkey`, which is required for the penalty transaction, allows it to be shared with the watcher without revealing `localpubkey`; even if both peers use the same watcher, nothing is revealed.
