Well.. given that he's your NPC, I imagine he can know anything about the FOH that he wants to know, as long as it doesn't involve blowing up the group that Dom is going to be spying on. :) I mean, the Friends of Humanity aren't... one group anymore. They suggest that they're one group, but they've splintered into so many factions that it's little pockets here and there and they're not necessarily communicating with one another, which means you can say some random sect in the boondocks is doing anything they choose.
