Yes, the help page needs updated to reflect the new usage. It was changed because some users were having trouble remembering how to keep the tab from changing on a reference click. This new method also could be improved so a user can temporarily keep a tab from changing without changing the default. I'll look into adding a key option (like Shift+click) which when held, the tab will not change.
