All this sounds great, Judging by what you have posted I would bet on him just taking the rest of his training in his stride without giving it a second thought.
Generally they start as they go on. If you have had an easy stress free initial training they rarely throw spanners in the works, If they are going to be complex they are generally complex to begin with and can be only suitable for experienced drivers.
