I am not making any points. I have just heard this take a lot of times and I have not been around London for over 10 years. If there is a point, it is not mine.
As for its relevance: "native speakers on English", etc.
It's not true. Where have you heard it?
There has been quite a lot of popular YouTubers spreading this.
One of them is Kurt Caz.
