Possibly missing explanation on difference between '&>' and '> word 2>&1' with multios in manual

[Jett Husher <jetthusher@xxxxx>]

Greetings!

I was reading zshmisc(1) on Redirections and stumbled upon the following
notice (`&> word` or `>& word` part):

> Note that this does not have the same effect as `> word 2>&1' in the presence
> of multios (see the section below).

aand then I never found the explanation how `&>` differs from `> word 2>&1`
with multios. I have read several times and multiple sections below as well.

Did I miss something or is the explanation really not present?
