can someone explain this image too please?

OK let me bring this together...
If you are creating your first Page you will get an Ad Account based on your Profile (Personal Ad Account). As soon as you are setup a Businessmanager you are able to create another Ad Account or claim others Ad Account.
First, you limited to 1 other Ad Account that you can create from your BM. Once you have running Campaigns on every Ad Account and you were successfully billed on every Ad Account you are able to increase the amount of Ad Accounts.
But your request confusing me, you write that you setup your BM and a new Ad Account was created automatically?
And you mentioned 2 other Ad Accounts. Are these claimed from someone else? Who have Admin roles inside your BM?
