Started reading the document tripped over a statement at the beginning:
"It is important to note that Chrome, unlike most browsers, holds multiple instances of the rendering engine - one for each tab. Each tab is a separate process."
This is not true and has never been true to my knowledge without restricting the statement. Chrome will open links opened in a new tab/window which point to the same domain in the same content process and it will start mixing different domains in the same content processes once a certain threshold is reached (whether this is a hard-coded upper limit on how many content processes may exist simultaneously or if this is calculated dynamically I do not know).
