Yes, seems so. Thanks!

If the PR is merged via the web UI, the PR number gets added automatically at the end of the subject line (although I can edit it before it gets finalized). If some people merge their PRs by pushing their commits manually, they might link to the PR review discussion manually by mentioning it in the commit message.

But our PRs are merged via "squash and merge", and we have it configured to default the commit message to the PR subject + initial comment. So if updating the commit message, it's good to update the PR subject and description as well, so it gets right in the end.

In this case, I guess the message from the commit is the most up to date and correct one? I can copypaste it from there when merging it, and I can leave out redundant manual reference to the PR.
