AFAICS the part about not having inconsistencies refers only to the
spectre of 'balance' being changed between its two conceptual accesses
in "SET balance = balance + 100.00". The risk that remains is that the
two updates could see a combined state of the two relevant rows that may
never have existed at the same time--which doesn't matter for this simple
example.

This is explained in the text, but it remains a little murky IMHO.
