Since the 2 caps are exposed to AC, current in alternating directions,
there is replating as well as deplating going on. The dire consequences are
apparently far enough removed in operating time that the replacement is
considered a successful substitution. Heck, even the correct replacement
eventually failed, right? <g> 

This back-to-back caps idea has been in use for many years and handed along
by many people for whom it has served satisfactorily. These are 'practical
experiments' in the field, conducted by these other fellows, showing that
the substitution does work for a long time (an admittedly imprecise
quantity). Their results show that, if the replacement is not exact, it is
of no practical consequence. If it works, it works...that is the charm of
amateur practice! <g>
