Are the examples on mutation in the documentation wrong?

I'm talking about the 'local mutate - request - update' one.

It says that the following code will just use the returned data, skipping the revalidation.

mutate('/api/user', newUser, false)
mutate('/api/user', updateUser(newUser))

From what I can see, the second mutate still needs false as its third argument. Otherwise, it will revalidate.
