BFA had achievements that were alliance/horde only.
They did not show up for the other faction.
They also did not have counterparts on the opposite faction.
For example - Horde only

Does not show up for Alliance.
However, i do not know if those 5 points would be gained on an alliance toon if a horde got the achievement.
My point being, that would be the precedent. If those ones shared points despite being 'invisible' to ineligible characters, covenants would probably act the same.
