Stacking Nobility Affiliations from Sworn Homage and Mark of Privilege?

I’m burning a character who is required by lifepaths to take both Sworn Homage and Mark of Privilege. Each lifepath grants a free 1D affiliation with nobility. Does the character get two 1D affiliations with the Nobility or do the affiliations stack to a single 2D affiliation?

They stack. Single affiliation.

but they could be used to create two unique affiliations also, right?

I burned up a clergyman that gained a 1d affiliation from Tonsured and a 1d affiliation from Vested. Since one indicated affiliation with a religious order while the other indicated affiliation with parishioners, I imagined the two were seperate from one another.

If you’d like. But the intent is that affiliation traits stack.
