You seem to be right. This Google Blog post[1] says "we do not have plans to delete accounts with YouTube videos at this time."

Would be nice if they would write that into the actual policy and don't just add a random sentence to a blog post.

If I remember right the original policy was to delete the YouTube videos and after pushback the YouTube exception was added.
