Youtube and Google+ have merged (in case you didn't miss the large outrage over that). It was after Google softened its enforcement a bit, and the enforcement was never good.

I also have multiple google accounts and had no troubles, but we're just anecdotes, we're not everyone. The few cases where it did happen were well publicized: http://gizmodo.com/5830463/if-you-use-a-fake-name-on-google%...

The fact that Google+ and Youtube accounts have been merged is common knowledge at this point.

Sure, the people probably did click "Update my details", but you can't expect regular users to read everything and google's actions sorta "sets you up for failure" in terms of identity.

Your argument that "I had no trouble so it's okay" is a bad one because it's an anecdote.

Your "evidence" that they help you manage multiple accounts is a good point. What I really meant is "Google has tried to prevent you from having false identities". Multiple accounts supports e.g. having a company Google Apps account and a personal account, or having a school account and personal, etc. Places where you have one identity and switch between multiple accounts.
