 trigger = {

	OR ={

won't work as I think you intend it, as it is now, you must simply own both. (ie. in this setup the "OR" is redundant)

trigger = {
		OR ={
		owned = { province = 270 data = STE }#Moscow#
		owned = { province = 272 data = STE }#Novgorod# 
		}
	}

will get you that either Moscow OR Novgorod needs to be yours.
