Well, passive isn't passive. It's things like infiltration, observation, slicing, disruption, sabotage. Some combat, yes, but nothing large-scale. More targeted, including finding targets. You would work with local cells, operatives from Alliance HQ, and a wide variety of informants - once you cultivate them, or convert your network. He sees you in a leadership role.
Coordinate is more of an analyst position, identifying areas and regions where Intel doesn't have data, and assigning assets to get data there. Coordinate is more back-end stuff. Passive is slightly more "pointy-end-of-the-stick" but shouldn't involve many slug-fests. It'll be MUCH more precise than SpecOps, though you might accompany a spec ops team on a mission for an intel reason unconnected with the SpecOps objective.
So, Passive would be more like what Trax used to do, only much more subtle, precise and targeted.
Does that make sense?
