I have no idea what Hagoromo's forehead marking actually is. About MS, in his talk page, someone gave the most sensible explanation I've seen so far. Since Susanoo requires awakening MS in both eyes, the marking alone can't be MS. What he did to Hamura did awaken MS, but for some reason it skipped right over to Rinnegan.
