It seems to me that ii-V6/4-ii belongs to _forbidden_ circumstances in 
strict counterpoint, because the progression involves parallel major 
thirds (5/3, 6/4, 5/3 above the bass ii) and so create a false relation 
between the 3 and the 6. If, as here (and in several other cases, 
probably), the problem is one of voice leading, it cannot fully be dealt 
with in term of harmonic roots and root progressions.
