Hello Pete,
Yes, when a user changes their name the associated account is put into moderation. This is due to our real names only policy, and the continuous attempt of people to use various fake names or company names. Once accounts are seen to be in compliance they are unmoderated, as is the case with your account. If you change your name back you will be automatically moderated, but then unmoderated after our moderators see their is nothing fishing going on.
