If the automatic message was already sent when it was on Legacy, then it'll be transferred over. All messages are counted as messages, even if they were sent by the automated tool. All existing messages that existed on Legacy get transferred along with the wiki's UCP migration.

It's only after it's on UCP, that the feature will no longer send those welcome messages to new users. But that doesn't mean it'll get rid of all the messages that were previously sent, before the wiki was moved to UCP.
