Not really. N+1 is about « to many » relationships. You would need at least 2 collections to run into that problem.
In sql equivalent, what happened would be more like doing a full table scan on each query instead of using an index ( and not even that, because pre-computing a total isn’t really like an index)
This kind of « account balance » problems are typical of the problems where transactions are really useful. But also historically the kind of problem where nosql techs do a poor job ( they’re more built with « eventual consistency » in mind than atomic or transactional behaviors)
