Consider using private AS space (64512-65535) only if you are multihoming with the same provider (eg: you have multiple exit points to the same provider). Note: you do not need to register private as anywhere. It's just a matter of mutual agreement between you and your Service Provider of what private AS you will use.
If you have multiple providers, consider using a registered AS number.
The idea behind the private AS is that you will negotiate the usage of a private AS with your SP. Say 64512. Remember your service provider has also a public AS (eg AS100).
The provider will see your routes within their AS with AS64512. When they will advertise your routes to any upstream AS they will strip out your AS 64512 and your routes will appear as coming from AS100
Imagine now using a private AS with 2 service provider.
What will happen if both strip your private AS and advertise with their own? Your routes will appear as being sourced from 2 Public AS numbers. Now that can still work, but is not correct/recommended.
I'm guessing he just means now you have a public AS registered with RIPE. As i said private AS is not registered with RIPE. RIPE does not even know about whatever private AS people are running (they are not visible in the internet routing tables)
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
