I would like to ask if we must only use 'just as' to refer to two actions happening at the same time or an action that happens after something.
1- The telephone rang just as I arrived home. (First I arrived, and then the telephone rang.)
2- Just as Michael finished his dinner, John washed up and made coffee. (First Michael finished his dinner, and then John washed up and made coffee.)
3- Just as Michael had finished his dinner, John washed up and made coffee. (The same as the two. But I am not sure if it is correct to use a perfect tense after 'just as.')
