Watched the video somebody linked on the matter, it does look similar to one of Daud's assasins disappearing (at least from a distance).

Considering you encounter Daud's assasins in the next mission, its possible that the figure is one of them keeping tabs on the High Overseer. Probably worth paying a little closer attention during the mission to see if any other mysterious figures can be spotted.
