FYI the answer in that link is from 2013, not sure how much it's changed since then but I doubt it's the same today.
One of the odd benefits of this is that old forum posts and discussions have a good chance of being relevant.
Although I will say lots of progress has been made in p2p message propagation (since this isn’t directly a part of consensus) which could definitely prevent orphan blocks, so you may be on to something in this case.
