Forum:LV Modulation?

the last ruling on LV modulation says that if the monster is SS in face down defense position, then the restrictions do not apply. Does this mean i can SS a Horus LV8 or Armed Dragon LV7 without having Summoned them correctly before (by sacrificing a Horus LV6 or Armed Dragon LV5)? can LV Modulation be applied to SS Armed Dragon LV10 if it was successfully SS before?
