The linked piece and video are very amateurish attempts to explain what has been well-studied by reputable linguists. We can do better. American linguist Lynne Murphy, married to a Brit and working as a linguistics academic in the UK for many years (and with a stint in South Africa) has a fantastic blog and book on the subject. Very easy to read and nobody has covered the subject better. https://separatedbyacommonlanguage.blogspot.com https://separatedbyacommonlanguage.blogspot.com
